I had this little cheap fish rubber stamp for a while. So I figured if I ruined it on this technique no big deal. But I didn't ruin it. I love this little toilet paper cast I learned to make in Technique Week on FAT with Michelle. She is a great teacher. Her directions are easy to follow. I painted it with lumiere paints. I don't think I am going to trim it but instead work it into the batting of a FPC and see if it will lay flat.
