I have been asked to piece together a quilt using blocks started by her mother 50 plus years ago. It is an eight pointed star that is hand pieced. I need to add the background fabric and piece enough of the blocks to make this quilt queen size. I have no idea as to how much to charge her. I have the top drafted out and plan on just charging her for the top and leave it up to her to have it long-armed quilted. Then I will bind it for her. Does anyone have any advise as to how much I should charge?
