Hey, I've never done a custom figure before, but after I discovered that some toy makers sell blank bodies to be used for custom figures, I've become interested in maybe trying to make some for myself.

However, I don't know what materials to use. I've seen people use clay, but I don't know how well that would keep on the finished product, so I was hoping anyone here who has made custom figures or at least knows enough about making them could recommend other materials for me.

Would it help if I shared images of characters I'd like to make customs of?
