Make An Easy, Organic Indigo Vat

In 2009 and 2010 I had the opportunity to study with natural dye master Michel Garcia. He is a marvelous and knowledgeable teacher, fascinated with using the chemistry of simple ingredients to create natural colors. One of the things that he demonstrated to us was to be fearless about the indigo fermentation vat. What a gift!

I was getting great and consistent color with my lye and soda ash and chemical reducing agents, so why … Read more

For National Tie-Dye Day, Resist With An Indigo Vat

There’s a holiday for everything so all hail National Tie-Dye Day! According to Vox, did you know that historians’ knowledge of early techniques similar to tie-dye is limited by the fact that textiles decay faster than most other artistic mediums? This means surviving samples aren’t easy to come by. “‘Some of the earliest examples come from Peru, but tie-dye seems to have originated independently all over the world,’ says Lee Talbot, curator of George Washington University’s Textile Museum.” We’ve created this National Tie-Dye Day how-to just for you to celebrate this sacred day to continue the tradition. Not sure which … Read more

We largely agree with this as most of our production colors start with an indigo shade that we dip. We seem … Read more
