You don't need corn starch to roll clay. All you need is some water if the clay happens to be super warm and soft, which it generally isnt. Water's less of a mess, too.
It's really cool. 💕I'm also doing resin art, but I think I'll have to work hard to catch up with you. If you have time, could you point out the problem of my work? I don't realize what the problem is. People don't see it even if a rabbit makes a work. Please save the rabbit from losing any strength....💜
