It just depends on how nice and intricate it is and how much it cost you to make it. If you post a pic of the quilts then maybe someone might be able to tell you how much it might sell for just by looking at the pattern. I would however make sure that you consider the money for the fabric. If you add up the cost of fabric and then add either 10-15 dollars for your time if it is a simple quilt top. you can always charge more depending on how nice you made the quilt. It is always about supply and demand, and where you are selling the quilt top.
