So interesting to see this question. It is the same question that I Googled and that lead me to this board! The answers were very similar to the ones posted here. Have enjoyed reading this board almost daily since then. I had to cut 10 inch wide by 80 inch strips for the border from such pretty fabric. It really slowed the progress of the quilt because I was so afraid to do it. I ended up using the marks on my cutting mat for the 10 inches, which I don't normally do, and then just kept sliding the fabric up as I cut. I lined my 24 inch ruler up with the 10 inch markings. Turned out just fine.
