White, gummy Wonder Bread isn’t just for peanut butter and jelly sandwiches. It’s a fun tool for making hollow forms in carving wax.
Just take some bread (Play-Doh works, too), mush it into shape, pierce it with a toothpick, and use the toothpick to dip it into molten carving wax (1). When you pull it out of the molten wax, spin the bread the make the wax thickness even.
After the wax cools, use a hot wax pen to build up thin areas (2), and use a wax file and carving tools to make the surface smooth. Pierce out the windows in the bead with a carving tool (3). When the outside of the bead is done, just put it in water to dissolve the bread and you have a wonderful wax.
