Sashiko THread for Denim Mending

Sashiko Thread for Denim Mending

I learned that many people come across the word “Sashiko” throughout searching for the mending technique. It isn’t quite popular in Japan yet (as long as I know), but I am very happy to share our Sashiko technique and concept through Sashiko Mending. In fact, I fell in love with Sashiko in a process of mending my denim jeans after all of Sashiko years. Besides some techniques, the Sashiko mending with Denim requires some knowledge to have the ideal results. One of the advise I can make it choose “appropriate” Sashiko Thread for Denim Mending. I am not talking about the “Right thread or Wrong thread” here. It requires some “try-and-error” process to find the best color of Sashiko Thread for Denim Mending.

Here, why don’t you save some of your time and “try-and-error” effort by reading my experience?

Working on the Denim Mending

I separate Sashiko Stitching on the pair of jeans into 2 categories. One is for Sashiko Stitching on the existing denim fabric, and the other is for Sashiko mending with patching other denim swatches to repair the hole or tear. In either case, I assume that the denim we stitch on is “Used”, hopefully, to extend to the vintage level. Sashiko Stitching on the raw denim without proper time in wearing them is not recommended at all. Trust me. I have tried it. Not only you will waste so many needles, but your hands will also be in pain for a long time. Let the fabric soften a bit, then enjoy the Sashiko stitching and/or Sashiko Mending.

 

Alright. We use the used/vintage Denim for Sashiko Stitching.

It causes another problem, though. The color from used/vintage denim is already “one-of-a-kind” and no single denim can create the exact same color. Although the color from nature is the closest color you can get, it isn’t still used/vintage enough. Especially if you are working on the Denim Mending, the color of thread can be the most challenging (and enjoyable) choice we have to make because there is no thread which will match that old, used, and vintage denim you already love.

 

Again, I am afraid that there is no color which is “perfect” for your denim (Unless you have the thread which aged as the denim did). The older & well taken-cared denim you have, the more difficult it is to find the thread. However, do not let you down. The Natural Sashiko thread will look natural after a few weeks of stitching and wearing it in your daily life. It is up to the stitcher’s preference what kind of natural color you may choose for the denim, but they usually match and fit after a few weeks. I have done more than 10 pairs of denim mending & Sashiko stitching on denim. Whichever natural color I used, it ends up with matching and fitting the old, used, and vintage denim.

 

Avoid using the synthetic dye with bright color (such as Red or Orange) Sashiko Thread.

Some synthetic dye Sashiko thread can be used, and I purposefully enjoy the bright result.

 

If the goal is to make the denim natural, then I strongly recommend using the Natural dyed Sashiko Thread. Here is a list of tips I have learned from my experience.

  • My favorite is Indigo Dye Sashiko Thread. The dark shade Indigo color will sink into the denim and will show up later on by Denim fabric fading. The light shade Indigo color looks pretty bright on the denim at the first glance. However, it matches the fabric day by day.
  • Yellow Colored Natural Dye is my second favorite, especially when I would like to have the vivid pattern on the denim. The natural yellow end up with the stitching with White thread. I avoid using the white thread because it sometimes gets too strong on the used/vintage denim. Of course, I use the white thread when I have the specific purpose for it.
  • The color of Natural Dyes fades over time. They do not bleed the color out, but the color changes over friction, sunlight (ultra-violet), and other chemical reactions.

 

Sashiko THread for Denim Mending
Light Indigo makes vivid stitching and dark Indigo will show the stitching when the fabric fade even more. The white thread sometimes shows “Too much” of stitching.

 

 

Appropriate Sashiko Thread for Denim Mending

My recommendation of Colors of Sashiko Thread for Denim Mending is above. I usually enjoy Sashiko Stitching with Natural Dye Sashiko Thread.

 

Then, how about thickness?

I always recommend using the Sashiko Thread manufactured by Coron and Sashi.Co & Keiko Futatsuya. The thread from them have the unique twist, and the result of stitching become not only beautiful but also strong in terms of mending. Although the thread is strong, the unique twist (soft and loose twist in comparison to the other thread) will naturally fit into the used/vintage fabric and will minimize the extra damage by using the new thread. Remember, if you make Sashiko stitching or Sashiko mending, the part around the actual stitched area will get weak in comparison to the mended area. The thread we recommend will reduce the risk of ripping the other parts of denim right after the mending. Well, the more hole we have, the more project we can work on… so it may make you happy, but I would like to enjoy the mended denim, at least for some period of time.

 

To be honest, the fabric you will stitch to can be anything available.

However, the thread will make a huge difference in Sashiko Stitching and Sashiko Mending. Get the best Sashiko Thread for Denim Mending, and enjoy the result as well as the process.

About our Indigo Dye Sashiko Thread

”What kind of Indigo Dye do you practice on the Indigo Dye Sashiko Thread?”

We received the question above on the Instagram photo in the Japanese language. The description on our Natural Dye and Indigo Dye are pretty simple, and we realize that it would be necessary to explain the Indigo Dye methods we practice. Any form of misunderstanding on what we do is the last thing we would like to have. So here is the Indigo Dye we practice on our indigo Dye Sashiko Thread (In 2018), and our belief in Indigo Dye.

 

*This blog is a translation & edited from the article “About Indigo Dye” in Japanese.

Natural Indigo or Synthetic Indigo Blue

 

藍染め刺し子糸

 

There are numerous numbers of methods to dye thread Indigo color. We roughly understand there are 4 main categories in dyeing methods using Indigo.

 

*Please kindly advise me if I am mistaken in the description. We are Sashiko artisans and not the Natural Dye Artisans. Simply, we enjoy Natural dye to create the color that matches the Japanese vintage fabric. We read the books and learn from the professionals. However, we aren’t perfect. 

 

Natural Indigo doesn’t dye the materials by just dissolving the Indigo Dye into the water.

When you use the Natural Indigo, the dye process requires “reduction (the word in chemistry)” with alkali agents. After this chemical reaction, the material touches the Indigo liquid, and then it gets beautiful blue (or green) in the process of the oxidation reaction. 

 

1. The Japanese Traditional Dye – Hon (Sei) Aizome

The Japanese before the year around 1865 made this chemical reaction happen by using the natural lye from wood ashes. Now, as long as I know, only a few percents of Indigo industry uses this Natural lye to proceed the process.  This is one of the most difficult & challenging Indigo Dye.

The master of “Sukumo” makes the Natural Indigo Dye so-called Sukumo by growing Tadeai (knotweed indigo = Persicaria tinctoria), dry the leave, then ferment them. After a good fermentation of the leave, the master of “Indigo Dye” mixes the Sukumo, Lye (wood ash), bran, and lime. The initial process of fermentation creates some odor, but when the process is completed, only a good natural smell will be sent.

 

We call this Japanese Traditional Indigo Dye with Natural Lye “Hon-Aizome” or “Sei-Aizome”, in rough translation to English “Authentic Indigo Dye”

 

In the 18 century, the industrial synthetic dye took over its role because the Japanese Traditional takes a lot of time and cost a fortune of money. Also, the Japanese government prohibited the Indigo farming during the World War II, the culture of this Indigo Dye once ended. However, even in that difficult era, masters in Tokushima kept the seeds of Indigo and passed down the tradition to today.

 

Personally speaking, this is what I love the most. I may love it more than Sashiko.

We have tried it, enjoyed it, but discontinued since it took so much time and cost. If we were a group of Dye Artists, we would have continued. However, again, we are a group of Sashiko artisans, and we needed to invest time and money into what we do.

 

 

2. Natural Dye with Reducing Agent


This method also use the Natural Indigo Dye including Sukumo and Indigo leave made in India. The difference is how to make the chemical reaction happen. The Japanese traditional way uses the lye from nature to make the Alkali agent. It takes a long time to prepare, and control the fermentation. The second method of Natural Indigo Dye is to use the same Natural Indigo Dye above, then use the synthetic reducing agent to make the similar chemical reaction occur.

 

This is the way we, Sashi.Co & Keiko Futatsuya, practice as of 2018.

As I mentioned above, we have challenged to create the Sashiko Thread with the Japanese traditional way. However, it was way too challenging to keep the liquid alive and keep the color stable. We learn that the Natural Indigo Dye with Japanese traditional method requires another lifetime commitment.

 

People use hydrosulfite and sodium hydroxide. 

We prefer not to use these strong chemicals to get the indigo blue color. Considering the troubles of controlling the liquid and the color, safety of hands and environment, we decided to discontinue the Indigo Natural Dye in 2016. Then, we come across the unique reduce agent produced by one of the famous Japanese natural dye manufacture (maker). Ever since we have been enjoying the beautiful Indigo colors.

 

It is with Natural Indigo Dye.

The color of Sashiko thread is beautiful. It is easier to control the Indigo liquid, and we can come up with variety of Indigo Dye Colors.

3. Mix of Natural Dye and Synthetic Dye

 

Indigo is a very popular color.

Some dye manufactures invested money and time into making an original Indigo dye, with mixing the Natural Dye and Synthetic Dye. This unique and original dye doesn’t require any chemical reaction under dyer’s control. It is ready to use by just mixing the dye. What the dyer has to do is to dissolve the dye into the water, and make a liquid to dye.

 

We tried this method several times.

However, we couldn’t have the result we expected. So we decided to discontinue this.

 

4. Industrial Synthetic Dye

Mass production of denim, especially jeans, was supported by this industrial synthetic dye. In 1865, the German Chemist worked on the synthesis of Indigo, and the easiness comparing to the Natural methods took over the market.

I have the very limited knowledge and experience in the (industrial) synthetic dye, I should not mention anything specific here.

The Coron Sashiko Thread #15 (Indigo Blue) is dyed with the synthetic Dye.

 

Other Indigo Dye Process all over the world.

The culture and history of Indigo Dye can be found in many regions all over the world. I know the very biased part of Indigo, and we try to come up with the colors we would like to use on our Sashiko projects. Please share your knowledge if you have one. I am happy to add information on this page regarding the Indigo Dye Sashiko Thread.

 

 

Definition of Natural Dye

Our Indigo Dye Sashiko thread

 

Well… I have said above.

We sell the Natural Dye Sashiko Thread, including the one we talk about here, the Natural Dye Sashiko Thread.

 

When we started working intensively on Sashiko mending with the vintage fabric and Boro, we couldn’t find the best suitable color from the synthetic dyed Sashiko Thread. After trying a variety of Sashiko thread, we reached to the conclusion of us dyeing Sashiko thread by ourselves. We started learning how to do it by try and error, starting some “easier” natural dye such as Madder and Tangala. It has been about 8 years since we started the journey. We are happy with our result with a variety of Natural Dyes.

The color for the vintage fabric & Boro, which the time flow made its unique color, required the natural color which also make its unique color by the time flows.

 

Our Natural Indigo Dye Sashiko Thread is in the category of (2) above.

We didn’t want to use the strong chemical materials, yet we didn’t have enough resource to focus on the Hon-Aizome. Some people may call it a “compromise”. However, we are okay with the result we have with the Natural Indigo Dye. After all, what we need is the color matching the project we are working on.

 

We call our Indigo Dye Sashiko Thread “Natural” because we use the Natural Indigo Dye material. Our decision of calling our thread Natural is either we use the Natural Dye materials or not. With this definition, we set the line calling our thread Natural by (2) and (3) in above description of each Indigo Dye methods.

 

Some people call an item “Natural” when a bit of Natural material is part of the process.

Some people call an item “Natural” when all of the materials and process are completed with natural materials and natural process.

Our decision is to keep producing the beautiful Indigo Dye Sashiko Thread with reasonable price with using only the Natural Indigo Dyes. I hope you understand how we dye the Sashiko thread with Indigo & also our philosophy toward the dyeing.

 

We will leave the correct answer to the definition of Natural Dye to the Dye professionals. It isn’t out of the field to discuss. We are merely making Sashiko thread to match the color to upcycle, repurpose, and enjoy the vintage fabrics.

 

Regardless, please do not forget the respect the Tradition and the praise for the skill and technique of the artisans. We all want to share the beauty of hand-crafting, and culture behind it.

5/15 Update for Kakishibu Dyed Thread

Ever since we first introduced the Kakishibu Dyed Thread in summer 2018, we have tried several Kakishibu Dyed in Sashiko Threads. The result of Kakishibu can be easily affected by sunlight, so it has been very challenging to create the similar color. However, we decided to offer the thread regardless of its small inventory number.

 

As of now, we have K○_1712 Series and a few left from the previous Series (K-177 and K-179).

Kakishibu Dye Professional

Ever since Sashi.Co & Keiko Futatsuya started challenging to dye Sashiko thread with Natural materials, Indigo Blue and Kakishibu Gold kept attracting us. The Kakishibu dye process requires at least 3 major conditions to make it successful.

  1. A lot of, tons of pure water
  2. Large space enough to prevent odor issues
  3. Skillful artisans to follow the strict dye process

It was very challenging to successfully achieve the Golden color Sashiko thread with ourselves. Then, in 2017, we got a fortune to come across the Kakishibu Dye Professionals in Gifu Prefecture, Kaki-Zanmai. They use the locally grown persimmon and follow the steps I illustrated in the first paragraph of this article. In their studio, people can dye what they would like. We asked them to dye our Sashiko thread, and we could add the Kakishibu color to our Sashiko Thread collection.

 

Here is a note from their Japanese website.

 

Kakishibu Dye

We provide a special Kakishibu dye made from “Izira Persimmon.” This Izira Persimmon is only produced in Yamagata city, Gifu Prefecture. The Izira Persimmon contains a lot of tannin, and had been well known for Kakishibu Dye. Natural & Local product for Kakishibu Dye. Kakishibu dyed product such as threads, fabrics, and papers are believed to have these functions; Anti Corrosion, Insect repellent, Antibacterial, Deodorant (Eliminating Odors), and Waterproofing.

Kakishibu Fabric, as well.

We have asked to dye the fabric as well. It is too costly to sell online for now, but we are happy to share the photos if you are interested. Please contact me so I can take photos of beautifully dyed fabric for Sashiko purpose. We are working on a project of Sashiko art piece with using Kakishibu Dye Sashiko Thread and Kakishibu Dye Cotton Fabric. Wait for the update 🙂

Shop Sashiko Thread wisely

 

Since Sashiko is getting popular, you can find many Sashiko threads available in the market. Make sure to be a smart customer there. You can shop Sashiko thread wisely in two perspectives.

 

1. Choose the best quality and purpose

The core concept of Sashiko is to mend, repair, and repurpose the fabric. Therefore, if you have a thread already, you do not need to buy the new one. However, if you are ready to purchase the new skein of thread, make sure that you get “Sashiko” thread. The Sashiko thread with the best quality will make your stitching last longer and will improve your stitching. Some of the thread is cheap, and some are the other sides. For example, our thread price range is from $12.00 to $30.00. Sounds a bit expensive? Some of the threads are expensive because of Natural Dye such as Indigo or Kakishibu.

However, the thread length is 145 meter. Yes. 145 meter.

I didn’t use up the whole skein even after stitching the entire denim jeans pants. It is how big of an amount for the skein of thread,

 

2. Know who you are buying from

 

Since Sashiko is getting popular, many dealers are jumping into the market regardless of its small size.

Let’s say, if you purchase a skein of Sashiko thread from a non-Sashiko related dealer, you may save a few quarters. There are many markets places that the many kinds of dealers are competing for the attention. However, these non-Sashiko related dealers will not provide you the advice or information regarding Sashiko. They are merely moving a product from left to right.

 

If this is a market in mass production and mass consumption, then I would understand that the principal of capitalism and fair business rules: the cheaper the better.

I would say, for Sashiko, it is more like “how to preserve culture” aspect instead of making the profit for the capitalists.

 

Please be part of the upcycling movement by choosing the good products from a seller who sells not only the product but also the culture behind it.

Sashi.Co & Keiko Futatsuya has been producing the Natural Dye Sashiko Thread for almost 3 years. We receive many positive reviews, and we are confident in what we make. At the same time, we receive many requests to provide a color sample for our Natural Dye Sashiko Thread Collection. Finally, I made several of Sashiko Thread sample Booklets. They are available online now! ~ Sashiko Thread Sample Booklet | All Natural Dye.

 

Sashiko Thread Sample Booklet

 

A price for the Sashiko Thread Sample Booklet is $20.00 !?

I set a price of $20.00 for the booklet. I know. It is expensive for a hand-made booklet.

The booklet itself doesn’t look like the one with $20.00 value. It is hand-made and we use all the Natural Dye thread so I hope it doesn’t sound like I am ripping you off. By its look, I would say $5.00 ~ $10.00 would be a reasonable pricing.

 

Then, why did I set up this pricing?

The answer is that I would like to sell (give) this booklet to someone who sincerely appreciates this booklet. Once I made the sample. In past, I have spread the Sashiko Sample Booklet to many people, pretty much everyone who wanted to have. It sold out very quickly, and I needed to ask customers to wait. One day, I found a sample booklet in a trash can…

 

Ideally speaking, I even would like to give away it free. It is my pleasure to share our Natural Dye Sashiko thread; what we are proud of.

 

After thinking a lot of the issues, I come up with the idea. I hope this deal makes sense to you.

 

Here is a deal I come up with.

We will not reimburse it and more

I will send you $39.00 store credit when the booklet holder purchases more than 15 skeins of our Natural Dye Sashiko thread in their life-time history. When I receive the order of this booklet, I will write down your name, and you will be eligible for the deal.

No need to purchase 15 skeins at once. I will send you the credit when you purchase the 15th thread. It can be anytime, even a few years later. No expiration date. I will count every purchase you made in past if you have already made a purchase from us.

 

We will reimburse the price of $20.00

After that, you will get $19 discount when you purchase more than 15 skeins of Natural Dye Sashiko Thread.

 

I hope this deal will make sense to you.

On top of this, Sashiko Thread Sample Booklet is a great sample book to keep in your drawer if you are in love with Natural Colors. With almost 50 colors we have created, we want you to get the color your project deserves!

 

Thank you!

Several ways to dye thread to Indigo Blue

We understand that the “Indigo” as the dark blue with this definition below.

  1. A blue dye obtained from various plants, especially of the genus Indigofera, or manufactured synthetically.
  2. Any of numerous hairy plants belonging to the genus Indigofera, of the legume family, having pinnate leaves and clusters of usually red or purple flowers.
  3. A color ranging from a deep violet blue to a dark, grayish blue.

1 – Benefit of Industrialization

The most common way to dye thread to Dark Indigo Blue is to use the synthetic dye. They usually manufacture and dye thread synthetically with using machines. Thanks to the industrialization, we enjoy the benefit of the reasonably priced thread. The result is not as “natural” as the other Indigo dye thread, the color is very similar. In our Sashiko Thread Collection, #15 is the Indigo Blue Colored Thread (dyed synthetically.)

Mono Color Sashiko Thread Dyed Synthetically Indigo Blue
Blue Sashiko Thread Collection dyed by synthetic dyes. #15 – Indigo Blue is the top one.

2 – Benefit from Indigo Researchers

One of Natural Dye suppliers we trust created a wonderful dye; a combination of natural and synthetic dye with ease in the process. There is no requirement of fermenting the dye liquid nor controlling the temperature. Although we do not carry the thread dyed by this amazing half-natural & half synthetic dye since we focus on “natural” when creating our own thread, I have heard many good things about this renovated dye from Indigo researchers.

 

3 – Natural Indigo Dyes

The most beautiful way, in my opinion, to appreciate the Indigo Blue is to use the Natural Dyes and dye them by hands. In this page, we are introducing new Sashiko thread, as the Natural Indigo Dyed Thread. Sashi.Co & Keiko Futatsuya prepared the liquid from powdered Natural Indigo, and let the liquid fermented in the controlled temperature, then dyed carefully by hands, only 10 skeins of thread each time. For Natural Indigo Dyes, there are mainly two methods/materials available in our capability.

Natural Indigo Dye Thread Process
Keiko dyes thread carefully by hands.

 

A – Indigo Dyes from India

It requires the regular controlling process, but easier than the option B. The Indigo produced in India made the Natural Indigo Dye process available for non-professional Indigo dye artists. It requires experience and strict condition control. However, when you follow the procedure appropriately, the result is very rewarding. As of 2017 Summer, we used this Indigo Dye from India to create this beautiful Indigo Blue.

Natural Indigo Dye Thread Product of India

B – Sukumo in Japanese traditional Indigo Dye

In Japan, people followed the beautiful process of making “Japanese-Indigo-Blue.” This dyeing process with Sukumo requires a lot of experience, deep knowledge, and a long time to invest. Even in Japan, there are only a few artists/artisans who follow the traditional Indigo dyeing. I know one of them and my head is down for their effort and beautiful result.

 

Our next Step to have Natural Indigo Dyed Thread

 

Our next step is, of course, to dye our thread with the Japanese traditional way to create the Japanese Indigo Blue.

We are not capable of creating our own Sukumo and Natural Indigo dye from the scratch, but we could purchase the materials and follow the procedures, then practice. We do not know how long it would take to make them as the products. However, as we have been acheiving so many goals already, we will make it happen as well. In fact, we started practicing dyeing the thread with Sukumo after we successfully produced the A1 & A2 Indigo Dyed sashiko Thread. Please wait for the update!
