I call these The Vintage Collection. I used scrap booking paper that I got in the Target dollar section. It was 12 pieces for a dollar.
These makes a wonderful Christmas Gift. It is easy enough that even children can do it.
If you have made a set of these email me or leave me a comment. I would be happy to post your picture and a link to your website.
