When I load a quilt, the top is pinned to the backing and batting about an inch down from the backing edge, so there usually is no trimmings from that side when the sandwich is removed from the machine. However; if I trim the quilt before returning to my customer all trimmings are returned with the quilt. The "yardage" of the trimmings might be a little different from what my customer would expect due to some fabric "shrinkage" as the sandwich is quilted. A densely quilted piece might not have much extra fabric left after quilting. Please do check with you quilter. Ask if there were any trimmings left, that you were thinking about using them, if any, for the binding.
