1. Any ruler that is not a Creative Grids ruler. These are amazing! I threw my old Olipfa ruler (with the lip that is to be used on the edge of a mat) away several years ago...I didn't want to curse someone else with that thing! The "lip" was not glued on straight, and so it was impossible to get a straight cut.
2. Fons & Porter quilting gloves, with the rubber dots. Threads stick to them, so you MUST take them off before trimming threads off your quilt. I use Machingers now, the Fons & Porters are in the drawer.
