If you are able to "quilt out the ruffles" then the person will not know how difficult it is. They will just see what a good job you were able to do-they don't learn or improve for the next quilt. Have her/him come and look at the quilt while you have it loaded on the frame. They will then easily see the problem. Looking at the quilt top off the frame usually doesn't show the problem as well. Explain or show how to correct the borders and then let the person decide if they will do it or let you. Its better if they do and learn to do it right.
