I had to rip out a partial row of long arming because my machien went crazy and the tension was off badly - I did my best lining up the design again but it wanst perfect - It was a charity quilt well I showed it to the lady who was taking them and she laughed and said first of all I wouldnt have noticed if you hadnt pointed it out and the people who get them will never notice - consider it a design element :-)
