Omnigrid InvisiGrip is a clear, non-slip material applied to quilting rulers and templates to prevent slipping while rotary cutting. It's ideal for beginners who are learning how to handle rulers and can be used with quilting, sewing, and crafting activities. It can even be applied to the back of cutting mats to prevent slipping. Once applied, InvisiGrip is clear and allows for easy viewing. If you ever need to remove it, it won't leave a sticky residue behind. One roll of InvisiGrip measures 12-1/2" by 1-yards.
