Dh &i went to a flooring superstore to look for something to finish flooring he is installing.
I saw one of those grabber things. i guesss it is used to help lay floor tile. I immediately thought it would work to help hold my large cutting ruler and keep it from slipping.
will test in next day or so and letr you know how it works. Quilt stores, JA charge $15 and up for similiar device. Another quilt thingy from an unexpected source.
