People tend to be more attracted to items with a clear price (instead of having to ask) and a description of the quilt. Before I quilted or knew anything about quilting, a description would have drawn me closer to buying a quilt.
ex: "Evening Star": custom made 100% cotton quilt with cotton batting; hunter's star blocks with needle turn applique flowers in the border and hand stitched binding. 60"x70" custom machine quilted and perfect as a sofa throw, lap quilt or wall hanging.
Keep receipts for materials in your project box (or estimate cost of scraps) plus an idea of the amount of time to complete. When someone asks, you can state the cost of the materials and the number of hours of labor to produce.
