Before I get too upset, maybe I goofed. My 50" x 50" wall hanging came back with puckers quilted in on the front. The back is fine. What would cause this? I squared up blocks before putting them together, pressed it very well so there would be no wrinkles or bulgy spots. This is a quilt I wanted to put in a show in January and, of course, now I can't. If I take out all the stitching, will needle marks show? Do I say anything to the lady who quilted it for me? Thanks for any advice/help.
