If your rulers don't have a non-slip surface on them, glue a few thin strips of fine sandpaper to the side that goes against your fabric. Always put your rulers straight up and down on your fabric, never slide them across the fabric. The suction cup handles made for seniors to help them in and out of the bath make great holders for your rulers. They are sold in the notions sections, but cost less when sold as aids for seniors on Ebay.
