This Creative Grid ruler is one of my favorite rulers that I use over and over again.  Its Curved Corner Cutter allows you to create perfectly rounded corners every time. Create curves with a 1 1/2", 2" or 3" radius. Ruler features 45 and 90 degree markings. Equipped with Creative Grid's exclusive non-slip grip, this ruler slides easily on fabric yet stays in place when pressure is applied.
