I was wondering if anyone had ever used Crayola "Model Magic" in the construction of a seat. My mother uses it for christmas tree ornaments like it was cookie dough, and it seems a lot like seat foam. It would be a good way to get a relatively lightmeight seat shaped to fit. I won't be using it at least for a while. I already have a seat for my kayak in production, but I thought someone else might be interested.

Any ideas?
