A friend let slip that she was natural dyeing playsilks for her daughter for Christmas. She was using only food dyes for the most part, coffee, spinach, raspberry zinger tea, turmeric, etc. So, of course, I offered some indigo from my pot! We rushed it a lot since it was my baby's naptime, and she had an hour and a half before she had to get her kids. I did one dip on each of these silks, one was dyed with turmeric, another with coffee (it started out as a nice tan color) and the others were white.
I will try one more short dip on one of the plain white silks and see how it looks but we are going for nice light or bright blues. The blues are mottled throughout the fabric and the effect looks like a blue/white sky. The coffee overdyed silk looks almost turquoise and we liked that one among the best.
