Make your own "polymer clay' that is self-hardening over night. Take 1 tablespoon of white glue, add a few drops of acrylic paint or India ink for color, if desired. Mix in a tablespoon of corn starch and 3-5 drops of vegetable or mineral oil. Mix well. If it is not thick enough to model, add more corn starch until it is of the right consistency. Add a few drops of water if it's too crumbly.
If you do not add a colorant, it dries to a lovely translucent white, which can be painted later or left as is.
To speed setting and to prevent drooping, blow dry your modeled object for a few seconds to set the surface. Store leftover clay in an airtight container.
