I've made two quilts with the ruler and love them both! It is a little extra work and a little extra waste but the quilt blocks come out perfectly, so I did not mind it. I would rather make my blocks a little bigger and square them down then having the blocks come out short. It's not a fast quilt but the results are amazing. I've seen them in made in two colors or many colors and love them all. Let's face it, you have to work and put your time in when making quilts but I love the process and the results. Good luck.
