I am interested, if my mojo ever comes back! Question - they demo using the lines on the cutting board. Donna Jordan uses the lines on the cutting board too vs. the lines on the ruler. I think for me and the type of quilting I do, lines on cutting board would be fine. But I have read numerous conversations here about No No No, don't use cutting board lines because they aren't accurate. I guess one could measure with the ruler first? Thoughts?
