I use the regular business sized envelopes, and I know many do. Also, when using baggies, the simple fold over baggies work best so you don't have the zip lock in the way. Also, several use the press and seal wrap or just regular plastic wrap. Personally, with the heat, I use just regular saran wrap. It is easier to get off the fabric. The press and seal is great, but I so hate trying to get the fabric away from it.
