sorry, I can answer a question or two, but prefer to keep my methods unique to me. Selling these helps pay my bills, and i just don't have time. Really all you need to do is learn how patterns work/to sew and have some ability to sculpt, then glue the parts together.
i use the tools made for working with sculpey, with the rubber tips on one end and metal ball on the other. Most easy way to smooth sculpey details and surface is to brush it with vegetable oil before you bake it, you can also sand it after too.
