I don't sell my work just for those reasons. I would have to charge more than the person could afford and they wouldn't be able to offer me what it's worth.
If you're selling, you need to make at least as much as what you would make at a regular job, actually more to cover your investment in tools, materials and space or it isn't worth doing. If people aren't willing to pay what a quilt is worth they can go to Walmart and buy a blanket. Also don't price your work by Walmart standards. Their textile products are made in places like Haiti and Bangladesh where people work in truly appalling conditions and are lucky to make a dollar a day.
