JoAnn's carries safety guards for rulers. Fons and Porter carries a cutting glove. You wear it on the hand that holds the ruler. That said I have cut myself numerous times due to carelessness. One time I turned to talk to my DH and the blade lightly went over my knuckles. Had to wear tight bandages to stop the bleeding. Luckily I didn't hit the quilt. I'll heal, the quilt won't.
