Are you putting the fabric on the right or wrong side of the paper? My first try, I tried sewing the fabric to the side the design was printed on, but when I flipped it over, I couldn't really see the lines very well. Then, I asked a friend and she explained the printed side of the paper is the back side of the design. That way you can see the lines (Duh moment for me). And she told me to be sure and use small stitches to perforate the paper closer together so it will tear easier. Also, make sure your pattern pieces are numbered and follow the order exactly. I'm not a PP expert, but that made the difference for me. I did a PP heart quilt for my mil that really turned out nicely.
