These are three ATCs I recently made for a swap. The squares on two of them are inchies I made out of caulk. It's the first time I've used my caulk inchies in my art. I like the way they look and plan to use them more in my art. I love using caulk in my art, it's one of my favorite art supplies. It's cheap, gives great texture, and is fairly easy to use.
