I had tried the little rubber adhesive backed feet and the sandpaper dots, but I was still searching for the perfect solution to the slippery backs of the quilting rulers. For me, this doesn't seem to be it. In a class I took 2 or 3 years ago our instructor told us about this product and how wonderful it is. I bought two packages to make sure I had enough to cover the backs of all my rulers--I have more rulers than I really need. The application didn't go quite as smoothly as the instructions indicated. It just didn't want to stick to some of the rulers (all of which were the same Omnigrid brand). It is supposed to work on the principle of static cling, I guess, but I ended up having to dampen some of the rulers to make this product stick. There is no adhesive involved. This is a plus when it comes to removal if you decide not to keep it on your rulers--no sticky backs--but then, maybe that would be the solution I am looking for.
