Hi! I met someone who mentioned that they blend in shredded toilet paper into their plaster molds. They start by painting a thin coating of pure plaster on the positive. (ie, just water and plaster powder, at a 70/100 ratio). Once that is dried, they blend in some toilet paper into another batch of plaster (I am assuming she blends it into the water, then adds the plaster to slake/mix). This mixture is thicker, and she sculpts it onto the positive to build up the mold. She said this makes the mold a lot lighter and easier to handle. She didn't know the exact ratio of toilet paper / plaster / water, she said she did it by feel. I was wondering if anyone here had tried this, any tips for how to do it, and in particular what ratio of paper:plaster:water to target. Thanks!
