Dritz should pay ME for the many dritz ezy hems that I have told students to buy (or as I have bought...have a few)! Seriously! It is my favorite tool! When I first learned to sew, we had to use the seam guage, measure, and iron every 2 inches. This will let me iron 8" of hem at once. One side does circle hems, and the other side does straight. I will stop the advertising now becase Dritz does NOT pay me!
