Quilters you need a safety device when using the rotary cutter! The Gypsy Grippers are good safety tools. The Little Gripper is excellent for the small rulers. I have one of the bathroom grippers and it doesn't hold tight as long on the ruler as the Gypsy Gripper does. I would never trust one of them to hold any weight push getting in or out of a tub/shower anyway. I have used my iron to put on my ruler if I'm without a holder and also used a bacon press. Being safe doesn't have to involve spending money, common sense will work fine.
