I like crocheting things that use up the odds and ends of yarn I end up with after a larger project. Some of the things I crochet are headbands, flowers, and butterflies. Here is a picture of several butterflies and one flower.
This is the pattern I used for the butterflies. http://www.freecraftunlimited.com/crochet-butterfly.html
The pattern tells you to chain 12 and fix it for the antennae, I chain 28 and tie it around the body to sort of define it.
