I made a SAS and used the PP method. I found it so much easier to line up all the points. Regarding the paper in the back ... well, if you want a fast and easy way ... a bit messy (not too bad tho). Once you're done your quilt top sew a seam as close to the edge as you can. Put your quilt top with the paper on it in a mesh bag (very small holes in the mesh bag) and toss it in the washing machine. The paper will be gone! It's miraculous! And it's all held together in the mesh bag. I lay it flat to dry and then iron it. It's a bit more work having to iron it, but in my world, I would have left the paper on it LOL I adore my hobby, but pulling off that many tiny pieces? NOPE!!!
