Having read up a bit on how to make my quilting rulers non slip I found a video that was recommending this tape for applying to the backside of the rulers to keep them for slipping when cutting fabric. I was using a 6" square ruler to trim 4" squares. The squares were just slightly over the 4" and so not very much needed to be trimmed off but I was having trouble getting the ruler to be stable with so little fabric to provide resistance to the ruler. I am sure this will work very well. I cut 1" pieces for both of my square rulers and one of my long rulers. Six pieces for the square - corners and middle and every six inches on the long one on both edges. I bought it at the local Pharmasave for $3.77 - 10 yards x 1" wide". Will have plenty for any other rulers in the future. Therese
