This fabric is very similar to the most commonly found non-skid fabric, although the fabric does seem a bit heavier than the commonly known brand. It is a flannel backed fabric coated with no-skid white dots. This version of no-slip fabric is white with white dots. It does seem to be a bit heavier fabric but above all it is definitely a comparable, quality product. The dot pattern does allow for more "wiggle room" when fitting various size slipper bottoms on the piece of Gripper Fabric than the foot print pattern.
Note: As of 11/08/10 this product is not listed on line except for the company's website. I did find the product at a relatively local Joann's Fabric and Crafts.
