Wow, what exquisite work ! I think the difference in suggested prices is due to the different sections of the country, and,possibly, rural vs urban. If your customer ordered 3 quilts from you this past year, she's happy with your work. I would tell her up front (or invoice) that the cost of materials & the cost of labor = whatever you decide.As an appraiser told me, your quilts are art quilts, not utilitarian quilts. In MHO, $1200-$1400 is not too much.Or check some of the shops around the country - they
charge for ironing the top, batting, & add on a price /inch for piecing, preparation & quilting and binding! Good luck!
P.S. Besides, due to poor weather onditions, cotton has increased in cost by 50%.
