I let the pots dry overnight and then put another bat on top of the pot and turn it over, carefully peeling off the original bat. I clean off the bat right away because it's a real pain if you let the clay dry.
After letting it dry for a hour or two I roll the bottom of the pot in a table and smooth the bottom off with my finger; I think it's important that even the bottom of the flower pot be clean and even, it reflects a real attention to detail on the part of the potter. Then I use a dull pencil to sign my name.
