At night if I'm tired of knitting or between projects, I crochet flowers to paint for the crazy quilt pieces. I leave the ends to put to the back of whatever I apply them to. On the red ones instead of using white thread, I used a variegated pink to see what would happen. Some are painted with Colorhue, some with Jo Sonia dyes, and some with Dynaflow. Sorry I can't tell you which. Once they are done and heat set, I can't tell--or remember.
