I use velum paper...you can get it from paper supply stores. There is also a lady named RaNae Merrill who sells it online. I'll try to find it ...here you go:

She charges a bit more than you can get it at the paper supply store for. If you look in the Dear Jane Cyber Sew thread, there's lots of talk about paper, where it's cheapest, etc. Problem is the thread is over 160 pages long...lots of reading to find your info.
