do you wish to actually be paid for your hours of labor? If so you need to set the hourly rate you would be willing to accept, then do some estimating on how much time you spent--not sure of the size of the quilt, but I would think on a queen size, with cutting, assembly, quilting, binding you would find yourself at least with 30 hours minimum. then add the fabrics/bat/thread. So if you set your hourly at $10/hr x 30= 300 plus materials. A friend just told me for a queen size t-shirt quilt she made she spent $238 for materials and quilting(VERY inexpensive quilting at $9/sq. yard!) Be prepared for buyers to balk--most don't understand the cost of materials or time involvement.
