I'm the type of person who might be forever bothered by the folds and puckers, so I would probably rip out the worst of them. (I sometimes rearrange the dishes in the dishwasher when DH puts them in there) I then would get a walking foot that works with the machine and then finish the quilting. I'd keep the quilt and use it, knowing that this was a practice piece and I'd get better. The first quilt I ever quilted myself 25 years ago is now in the trunk of my car for emergencies and picnics. I didn't use a walking foot either. You'll be surprised how much easier quilting is with a walking foot.
