I use the non-skid shelf lining under my rulers so they don't slip when cutting material. I just use a strip horizontally, just enough about a 6x1 1/2" strip. I put the strip where I would place my hand to hold the ruler between the ruler and the fabric. Usually can get a roll of 2 yards for a buck or 2. It's also great for placing under meat/cutting boards on your counter tops so the boards don't slide. Especially, the ones kids sell for school fundraisers, the really thin ones.
