Not really, but it does make the cutting much easier and I can do more quilts because I don't have to spend so much time cutting (and recutting because I missed the correct line on the ruler--even when I taped it). Now I don't have to worry about the V-fold, not so much squaring up, etc. And since I'm math challenged, its a real pleasure to use since it includes seams and the 7/8th with triangles and even cuts the infamous dog ears!
