Your quilt is beautiful! I would remove the quilting from the back of the quilt (less chance of damaging the top). If you decide to have it quilted by another LAQ you may want to provide new batting and backing so you can give her/him enough to work with. I have done several quilts for people who were unhappy with another quilter's work and as long as they removed the first quilting very carefully, they turned out beautifully. Good luck at the fair!
