You can get it at many arts and craft stores...not sure what you have by you. It is in a generic looking green box...kind of 70's ish looking. It is a peach colored clay. It holds up a lot better...an rebake several times without becoming brittle. It is easy to work with much easier than regualr Sculepy i think!
I can't fave all your sculptures and I can't comment all of them, but each one is so amazing I can't even begin. I love them so much and I really, really hope I get that good one day. Seriously, I was slack jawed the minute I seen them all.
