I am a longarmer. In a ideal situation, when you take your quilt to a longarmer. The longarmer should look the quilt over before the customer leaves the quilt with you. If the borders are wavy, the customer has a choice to either fix them or pay the longarmer to fix them, wavy borders cannot be quilted out. If there are seams that have been missed same thing. I would hope there is a good relationship between the customer and longarmer. As a longarmer you never want to make the customer feel like their work is bad. If we didn't have quilters we would not have any business. Hopefully it can be a learning experience. I am just one longarmer, but in the quild that I belong to we usually all agree that things that make work for the longarmer and are not going to make the customer happy should be discussed with the customer.
