For the kids, we made a clear glycerin soap with toy fish embedded inside. (They'll be sure to wash and scrub trying to get at the fish.) Then we made a scented oatmeal soap for the adults. Cardboard jewelry gift boxes were used as forms to make the soap. Then, after we were done, we used the boxes to wrap our soaps and give as gifts.
Cut the wax paper to size so you can line the inside of the jewelry boxes, making sure that the edges extend beyond the box. Use your fingers to spread a thin layer of coconut oil on the wax paper. This will help the soap peel off the wax paper easily after cooling.
Follow the same procedure, but use bar soap instead of glycerin soap. Additional ingredients include: 2 tablespoons of rosemary (or lavender), 2 tablespoons of ground oatmeal (use a blender), 1 tablespoon of coconut oil and a few sprays of perfume or cologne.
