It is so hard to give advise to someone that knows what they want. But it is their quilts and if they love the work they did, then accept it and move on. Their next quilts (if they decide to another) will be quilted so much more, and they will make that decision. Not someone else. Yes it is hard, but life is hard. We all must find our own way to doing something. Good luck, and be proud that they wanted to learn to quilt with YOU.
