Looks like we are all "hooked on rulers". Yes, indeed they help us to be accurate cutters and square uppers. It make me wonder how our "grandquilters" ever made an accurate cut or square block with paper templates. It only adds to my amazement and admiration at what beauties they created without out plethora of tools. No, I am not willing to give up my tools. I suspect our "grandquilters" also were more patient than some of us may be.
