Color evaluation - low temp dyeing

The second session of the dying workshop was on color gradation. This time I used turquoise blue. The first cotton fabric was put into the dye and left to sit 15 minutes. Next a 1/4 cup of soda ash water is added and a new piece of cotton cloth. After another 15 minutes another 1/4 cup of soda ash is added and a third piece of cloth is added.
