The hoarder in me couldn't bear to throw them out right away, so they sat in a pile on my kitchen table for several days. Late one night while I was baking cake layers, I wound them up as you would make a yarn pom pom (just not quite as dense), tied it off at the center, trimmed up the resulting puff, and hot glued it to a hair clip. So easy, and it was a perfect match to the rainbow dress (since that's where the scraps came from, of course).
