Definitely rip out bad quilting! I took three quilts in to be quilted and the "professional" quilter got all the backs with the wrong fronts. Plus the quilting itself was absolutely horrible -- it made the pretty quilt top look ugly and the thread tension was off with lots of bird nests on the back. I was so disappointed. But, yes, I did rip out all of the quilting on all three quilts and, 8 months later, they're still sitting there waiting for me to make a decision on how to proceed. Some day I'll be brave and take them to someone else to be quilted.
