Funky Fiber

Three little rolls of funky fiber in Mother Comfort's crafter's extravaganza. When I first saw them, my heart did a little jump, for they are beautiful! Unwisely, I thought they may make a good thread for the edges of my little hearts, but the thick parts don't want to come through the felt and the thin parts deteriorate from the pressure of trying. I've considered I may have to just crochet something with them. Have also considered gluing them in a design against black felt so the colors will all stand out. I may, on the other hand, just keep looking at them on the roll, they delight me so!

What would you do with them?
