I quilt for friends and the public. If it is a queensize and it was easy and machine pieced. I charge about 325.00.
However most quitlers at our guild charge by taking the width x height and multiplying it by one cent. A little high to me. So it is at your disgression. What time you put in it, who it is for, etc. This is such an opened ended question. In general, I sell twins for 100.00, full for 150., queens for 200, king for 250.00. Maybe that's why I get so much business LOL. YOu can also google it and get more ideas. GOod luck. The quilt was lovely.
