As for pricing, you should certainly expect to recoup the cost of the materials. Then, try to figure out the time you put in to it. Choosing fabric, washing and ironing fabric, and of course all of the cutting and sewing. Keep track of your time, you will be amazed. If you use the materials x 3, you will be only giving your labor materials x 2. So, $100 in materials = $200 in labor. What is your labor worth? I don't think x 3 is adequate, unless you are making very basic tied quilts. In some markets, you could only sell small tied quilts made of inexpensive fabrics. In other markets, you can do much better. I think I would scope out the market and work from there. If you can get $1,000 for a quilt, get good fabric and figure out your labor costs- a much nicer quilt than the $200 version.
