Sadly, I need the glass for some of my ripping. I have the large one with the light that hangs around your neck (got it at Joann's). It helps, but not as much as a pair of new eyeballs would! Also, I bought a small electric razor (for mustaches, I think) at a quilt show, and it rips seams very quickly and neatly. You can get one through Nancy's Notions, or possibly through your local Sally Beauty Supply store.
