I'm convinced I NEED one of these rulers! At first I was thinking it was another gimic tool that I didn't need. (I have quite a few of those in my sewing room - LOL) But just last night I spent two hours trimming fabric on 192 pp sheets. I tend to be a perfectionist. After reading this post I realize that a lot of that time was spent ensuring I had the perfect quarter inch. Thanks so much for the post!
