Ditto to Quilter 1942. Took a class from Carol Doak and that's the best trick she taught us. Use the long basting stitch to check out your stitching - easier to rip if your special points, seams, whatever don't match. I never tear the paper out until one unit is stitched to its companion - that way the 1/4" marking is visible on the paper when I attach them. Be careful - PP is addicting!!
