Just posted this on another thread. One lady quilter charges around $240 per sq ft for commissioned quilts, patchwork or hand embroidered, depending on the complexity of design. I don't know if that includes the fabric, but does include quilting. She seems to get enough work. I know of one machine embroidered quilt sold for $60,000 and another for $20,000. Makes the head spin, eh.
Price will depend on how badly you need to sell yours, as not everyone appreciates the time spent making them, and the cost of fabrics. I tell the tight-fisted, if they want to pay peanuts, then get monkeys to make it.
