I am always looking for things I can use as paint tools for my mixed media work. I found these rubber drink coasters at Target. They come in a pack of four in the kitchen section and cost about 3 bucks. I then stuck them to a piece of clear plexi glass with a glue stick. I apply acrylic paint with a cosmetic sponge and they make great prints on paper or fabric. When I am done stamping, I just peel the coaster off and wash in soap and water.
