I just can't get enough of them!
I actually made these last year (after seeing some projects in this site).
At first I used clay but then I started to stick anything interesting in. :D
My best ones are the four-leaf clover, the roses, and the pie one (no individual photo).
Really, whoever started this project is a genius!
