Make beautiful plaster bowls with plaster gauze. METHOD: Place a bowl, or the object you are going to cast, on a covered table. Cover the bowl with plastic wrap. Cut appropriately sized pieces of plaster gauze. Dip one piece of gauze at a time into water, pick it up and squeeze between your fingers to get rid of excess water, and then place it on the bowl. Repeat with all the plaster gauze strips. Let the plaster dry, and then remove it, as well as the plastic. Decorate the inside of the bowl with metal leaf and paint the outside with Hobbylack. To make the bowls in the picture, you will need two packs of plaster gauze.
