I make custom draperies and bedding. A queen size custom quilted bedspread would cost $1000 or more. It's over $400 to have the custom quilting done. So, perhaps your friend has already priced a custom bedspread and thinks the $800 quilt would be a great deal. Don't hesitate to quote it and if they have questions explain the pricing to cover it. My husband says I'm lucky to make a $1/hr on the window treatments since I am such a stickler for precision. That's why I love quilts!
