I longarm and I would definitely tell the customer if something wasn't right...I had a lady send me one by mail and the borders were very wavy ...it was going to be hard to make it square...I called her and she said to go ahead and quilt as it...she was a very picky customer and I didn't want to be at fault if the job didn't come out right...I had to pull the top and stretch it more than I wanted and this caused some boarding on the back...I was happy I had advised her ...
