I found a printable ruler at Spark people. It can be as long as you want or you can cut it short. I printed it up on card stock and on regular paper. I put it together and taped a long piece on the edge of my cutting table for measuring yardage. I sprayed it with clear paint to keep the ink from running. I do't have the link but I think you can search it on the site. I will have to try the other links.
