I have several rulers bought over the years. The one that I use the most (all the time, actually) is the 6 1/2 x 12. I have almost worn the markings off, and will be so upset when it can't be used anymore. I needed a 12 1/2 x 12 1/12 ruler to square up blocks for a class I was taking. I got a set of 4 at JoAnn's with a coupon for about $17.00. Thought I got a good deal!!!
