Last year I discovered a huge inventory of plastic buttons. I have been using them in my classes because they are an inexpensive bezel too!
Here is just one way this button/bezel can be worn!
I attached a bail to the back of the button and then just strung it on this wire with glass and metal beads. If you want to know a little more about bails, I did a blog post last year showing you how to use them. The images in these buttons are from Cari Lopez. Her blog has so much wonderful art to see and purchase!
