I use a paper called 'Easy Piece Foundation Paper' made by Zippy Designs. I just Googled Easy Pieced Foundation Paper and it came right up for places to get it. It is easy to see through, easy to remove and goes through your copier. It also says u can use it for needlepunch(although I've never used it for needlepunch). It is great. I have a lot of it. I don't remember the cost, but there are 25 sheets to the pack and they are 8 1/2 x 11 - the ones I have anyway.
