First Mug First Mold Progress: THE MOLD IS DONE!!!! - Other Crafts

That was enough to ruin my first two attempts at making a mold, and still enough for my third successful attempt with some left over. One of the first things I did when buying plaster was to immediately transfer it to a plastic storage box - "totes" I believe they're called - with a lid that clamps on fairly securely. This made it easier to scoop out the plaster and it kept it nice and dry. If you're going to use plaster of paris I'd think in terms of getting three five-pound boxes. Better to buy too much than run out in the middle of the project. I'd really try to get pottery plaster, though. It's much better. Does that sound about right to everyone else?
