Out of stock. Will be back soon. For the traditional reactive dyeing process you will need dye powder, soda ash, urea (opt.), fabric detergent (opt.), dust mask, gloves, and safety glasses. Dye Mixing: For the color swatch, we used 3 tsp Fire Yellow dye powder to 1/2 cup warm water with 1/2 tsp urea. You can use less dye powder to get a lighter hue. [Fire Yellow is a homogeneous dye.] Use your own reactive dye procedure or one of the dyeing procedures from the links below. Have fun!
