I did not see a one-use ruler, but I did see a 7" X 12" rectangular template with a cutting curve built in. I offered to help a friend cut for a group of children she was teaching to make quilts, thinking it would be 5, 6 or 6.5 inch squares. When she said 7" squares, I had to re-think how I would do it. Sometimes I can get off the mark when lining up fabric with a long ruler that is 8" or 6.5" wide.
