A little trick I discovered helps me. I have all 4 of the paper patterns pinned firmly together so they don't slip around. Then I take the thread out of my machine. I change it to the biggest basting stitch and sew with the empty needle over all the fold lines inside the pattern. Now I have a pattern with hundreds of little holes in it for guide holes.
This really has helped me when I am lining up the fabric as I can see my next "line" with the basting holes.
It also helps me fold the paper over when I am trimming for the next section too if you follow Carol's instructions for the pre-trimming method.
Hope this helps someone else too.
