I just purchased a ruler that might be of help to you. It is clear 6" X 27 1/2" long that has a cutter built into it. You use the palm or whole hand to push the cutter up & down. They are on the internet altho I purchased mine at our State Fair from Patrick Lose who had a booth, fabric & patterns there. In fact he cut my fabric with one & sold me on it! I have used mine & believe you would be able to work this ok. The cutter on it is kind of round & easy to use. It has small strip of sandpaper on the back to help it stay in place. It is pricey but I feel I'll get a lot of good out of it. .
