I think your prices are pretty low too. You have to remember that if you are going to sell hand made quilts, you are marketing yourself to someone that wants to buy a handmade quilt. Some customers may want your prices to be the same as a comforter at Wal-Mart, but they are not your target market. You want people that know what it costs to make soemthing homemade. This may mean you will not have a stampede of sales, but you'll have a higher caliber of customers that will return to you for gifts etc... If you sell your items for 'cheap' then that is how customers will perceive your end product.
