Using grid lines on cutting mat?
I am left handed and lay my fabric on the mat and use the lines on mat to line up my fabric and lay my ruler down on the mat and line the ruler up with the lines top and bottom of the mat to cut. A person at the guild told me never to use the lines on the mat to measure. I have been doing my cutting this way for ever. Is this wrong? I don't know how I would do this otherwise. Thanks for your help.
