I made a quilt top a while ago. It is 102 x 120” for a tall king size bed. 120” goes across the width of the bed. I chose a print for the backing and joined three widths (no problem). Unfortunately, I did not lay it out and pull it on the bias to square it up (too big). Yesterday my husband and I folded it along the 120” side so I could take it to a longarmer and it was off about 3” from top to bottom. The Longarmer, who is new to me, is putting the backing on the roller on the 102” side. Will there be a problem with her getting the backing square or should I go and get the backing and bring it home and lay it out on the floor and square it up. Hope I made myself clear.
