Ok...so I just watched the first 2 segments of the new Quilty show on QNN TV. It features Mary Ann Fons daughter, Mary. Quick little show for newbies. In the second episode she teaches a friend how to use a rotary cutter, teaching her to line up the ruler with the grid lines on the cutting mat.
SO...now I am wondering if I have been doing it wrong (or harder, or less precise) all along? I was taught to use my ruler for this. However, she was cutting 2" squares by placing the bottom straightened edge of the fabric on the left/right (horizontal) line of the mat and then lining up the ruler with the correct north/south (vertical) line on the mat and then using the ruler as the straight edge, cutting.
Do any of you do it this way? Is it more or less precise? Inquiring minds want to know....
