Carving the stamp after it has cured is similar to doing an eraser stamp
. Prepare your stamp as in Step 2 and let cure for 24hrs. With a pencil draw your image onto the stamp. If you want to have text on the stamp it needs to be a mirror image. Carve out the shape using a utility knife. Take your time and work carefully, unlike the stamps in Step 3 you can't smooth over your mistakes. Test out the stamp as you go to see which areas need more carving.
