Thanks so much for the compliments. Bunny, I have to be honest, lol, I turn the soaps over and stamp on the bottom side. The side you can't see is the bumpy side. Now you know my deepest soaping secret, lmao! E, I wait for about 12 hours. I usually stamp right after I unmold it. It really depends on how hard your soap is as to how many times you hammer. I usually hammer about 6 times. If your soap is soft, it will spread, lol. Be careful!
