I have basically Omnigrid rulers because those were the first acrylic that were sold to quilters. I have a June Taylor Shape Cut Pro that I don't like having to fight to get my rotary cutter in the slots.
I made a quilt that had a couple of hundred flying geese and I LOVED EB method because if you stitching off just a bit, you can fix it before the final trimming. Just have to pull out an old book of her's to find out the size of squares I need to cut. Saw something recently on F&P which was even more confusing for making the geese.
