I have a ruler that I brought in 1999. It is a 6 1/2 by 24 and I love it. The numbers and lines are starting to disappear but I plan on using it as long as I can. I have a smaller one but only use it for trimming. I also have a 8 1/2 by 24 and then there is the tons of other rulers that I had to buy for special quilting classes. Too many!
