I was in my LQS recently & the lady who owned the shop told me that Long Arms are intended to work from left to right. She said that the stitch would be different on the back of the quilt, if you went back...from right to left as with a pantograph. Is this something any of you with long arms have experienced? I would have thought you could go any direction with no difference in the stitching. We were discussing a Tin Lizzie. Maybe the Tin Lizzie likes to got from Left to right???
