I put together this set of brooches from Etsy. To do it, I looked at just about every recycled felt brooch on Etsy. There are fabulous things available. My favorites are by WanderingLydia and Woollyfabulous and mdemag.
But I love them all... It is interesting that even when I set out to shamelessly copy someone else's work, mine turn out different. For example: I was really just copying the work of mdemag but I ended up putting a lot more buttons on mine, and started making squares instead of circles.
