Here are some useful points for pp:
1. I use regular copy paper, nothing special.
2. Use a short stitch because they make removing the paper easier and the fabric won't move.
3. Do not remove the paper until the piece is completely done!
4. Remember to trim your seams (once they've been sewed)to 1/4".
5. Press and starch each piece right after you've added it.
Hope this helps. I absolutely love pp. And it is addictive, in a wonderful way!
