I'm needing some help on this pattern - specifically with cutting the triangles. The pattern instructs you to use a 12.5" square ruler and having the point up as you face it - place tape at 11.5" down from the point and at 16.5" down. I did this - but when I starrted cutting a few minutes ago - my triangles are not the size they are supposed to be (almost half inch off)...so obviously I've done something wrong :thumbdown: The good news is that I can salvage the project be making it the smaller size. Is there an easier way to do this???
