I'd keep it, you may need it for something. I had an old 6" by 24. I liked the markings on it. But I ran over it with my wheelchair. LOL, so I got a new one. The first quilt I made was all out of whack because it had different markings on it, and I made the blocks the wrong size. I've kept my old one. I still use it to make sure I'm reading the new one correctly. And now I have three!......
