DIY: Indigo Dye with Cara Marie Piazza

Our good friend and Botanical Colors customer, textile artist Cara Marie Piazza, was recently featured in Gardenista using our rich indigo. Writer Sophia Moreno-Bunge caught up with Cara in her studio and wrote: “Indigo is an ancient color, a natural dye extracted from a plant of the same name, and the only true blue dye in nature. It’s been found in ancient Egyptian mummy wrappings and was so valued by the Romans as a luxury product, the story goes, that the only people who knew how to dye with indigo were hidden away in the forest,” says Moreno-Bunge. “Because of … Read more

Mordant Monday: Chestnut, Fustic, Iron and Indigo

This week’s Mordant Monday focuses on Chestnut. We used Chestnut extract in our gradation and absolutely loved the combination of Chestnut, Fustic and Iron with Indigo. This gradation is slightly different than our previous experiments. This time I did not overdye with a warm shade like Madder, to get corals and pinks. I wanted to focus on green and blue. Like previous examples, when a tannin is combined with other colors you can get exciting mixes and beautiful color blends that harmonize and are perfect for patchwork, creating gradations and stitching. If you are a yarn person, many of these … Read more

Mordant Monday: Walnut, Madder, Iron and Indigo

Black Walnut Juglans nigra is one of our most interesting tannins and it’s a color that’s native to the North American continent. The entire tree contains color but it is in the green hulls that we find a strong concentration of dark tannins yield light beige to golden brown on cellulose. On wool, black walnut really shines and makes a rich brown shade. Walnut Hull Powder from black walnut (Juglans nigra) is a common source of brown dye throughout North America. The fleshy hulls are full of tannin, juglone and other pigments and are the primary source of the dye. … 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
