Actually, use Eleanor Burns ruler and itis even easier than that. Her rulers help you trim it to just the right size. The hardest part for me on that block is to be sure and put put right sides together to cut the diagonal pieces. That is the one part I miss at times and have to recut. I is that reversing stuff. My brain has issues with it. She also has you cut strips, then cut your pieces from there. check it out on her website.
