Why does my clay shrink and pull away when covering an aluminum foil core
Hi everyone! I’m running into an issue when sculpting over an aluminum foil core. Whenever I lay the clay over the aluminum base, it ends up shrinking and warping/cracking like this: [Attach your photo here].
Is this happening because:
It isn't drying/curing properly?
The layer of clay over the foil is too thin or too thick?
Polymer clay / air-dry clay shouldn't be wrapped tightly over a solid aluminum base?
I'd love to know what might be causing this and how to fix or prevent it. Any advice or tips would be greatly appreciated
