I just learned to use the AMAZING Mold Putty. I love the fact, it has a Part A and a Part B (both in a clay-like material). Knead both parts together and press the item to be molded into the putty, leave for 20 minutes, pull the item out and you are done. It is food safe. If it is a little piece you do not have to mix the entire amounts. Save it for later. Just wash the mold before using it.
