If you sgraffito while the work is wet, you will remove more of the Crackle Base than you want. For thinner lines, let the piece(s) dry a bit and then sgraffito with a tool of your choice. I used a pencil for this project. It's a bit difficult to get the piece on the trivet without moving the enamel. At times, you may want to correct this shifting after the trivet is in place.
