The best way to have a good idea is to have lots of them.
Putting felted flowers on elastic headbands has been my latest felting endeavor. Margaret brought Lisa a flower headband made on an elastic band for her birthday and immediately I thought why not felt flowers instead of fabric. Abby received the first one I made with two different types of flowers. Since then I have made a few more with single flowers, rows of flowers, etc. (shown above).
Carol wanted one with a bug. I wonder if a butterfly would fit the bill?
