There are so many neat things you can find on etsy. It's really pretty amazing. One day I went looking for things with a base that a button top could be attached too, and some wonderful things turned up!
Of course, I wanted them all, but thought I'd start with these antique brass hair clips.
This was so simple to make--all I had to do was glue one of these adorable pink buttons with a recessed back to the base.
