Here are some cards that I made recently for my Etsy store. Instead of using only thin papers, I added some dimension for them. The ones with squares are made from memory play cards. I covered them with tiny scraps of paper, all my own designs. The one with the star has a handmade polymer clay button on it. Remember, when I made these? (Some are available at Etsy too)
Here's a close-up where you can see the dimensional blocks better.
