I have to have the right size ruler for what I need. Not one one size bigger. I am making a block that is 7 1/2" unfinished, I want a 7"1/2 square ruler. I don't like to make do, I'm so over that from the lean years of having to. I'll wait until the right tool is found before I will start cutting or sewing that particular unit. I do have an extensive ruler collection and it's wonderful.
