Here's advice for making marshmallows out of oven hardening modelling clay. I am not the best clay artist (far from it) but I have some tips for you.
For polymer clay crafts you need the clay, an oven and a sharp knife. For cleaning up the dust some q-tips and water. Then just swirl three bars of clay lightly together and cut with a sharp knife.
TIPS FOR MODELLING CLAY CRAFTS
- Polymer clay/modelling clay gets dry and hard relative soon after opening the package. You can temporarily soften it to be able to mold it with a blow dryer's hot air. It won't last long though so you have to be quick after that.
- Clay collects easily all the dust floating in the air. You can clean up the small particles of dust at least out of the surface with a wet q-tip.
- You can stick the headpin in already before the oven so you don't need to drill a hole for it.
- Handle the clay as gently as possible if you want the form to hold until the oven.
