Hi yall,
Well, you've bought the Sculpey. And depending on what its used for, it has its upsides, and down sides. This here site has a lot of useful tips on it, if you tend to be the figure sculptor type and scratchbuilder.

I'm afraid that if you want to sign up for the forum there, you might wait awhile. I think when I first signed up, I waited forever for a reply. So I forgot about it, and wondered who signed me up for it in the first place
If your in to doing scratchbuilt ships and parts, then yeah, it'll work. Just don't be expecting to get it right first off. I've worked with Sculpey 3, Super Sculpey, Fimo, and an Australian brand called Modelene for 5 years. And still haven't got the knack of totally square parts

I still tend to do any scratchbuilding in plastic.
I'm no expert. But the Clubhouse and its forum should be able to answer any questions about Sculpey you might have.
