Each composition is made up of fabrics that were in the same dye pot. The differences in the tones are due to the different fabrics I put into the pot. I love these subtle “colors”. The yellows were from woad plants. The browns were from green persimmons over dyed with indigo. I especially find myself liking things that have almost no color at all. One of these is from oak galls. I can’t remember all the specifics but I like to put dyed fabrics in a bath of iron water to “sadden” the color.
