"If you plan on doing cross hatching a lot, the straight edge tool from Lowe's or Home depot will be invaluable. It is a long two inch wide metal ruler. I have the 4 ft one and the 6 ft one."
Way to go, OnebyOne! I thought I was the only one who buys rulers, squares, miter tools, etc. for quilting at Home Depot & Menards. They have lots of rulers, etc. that work great for quilting. I've even coveted their rolling tool bags for transporting sewing machines - a lot heavier duty than the flimsy rolling carts made for sewing machines.
