I have charged everywhere from $25 (wall hanging) to $1350 (queen) for a quilt and had very satisfied customers. Remember, even if you are using your stash, the fabric did cost you and will cost to be replaced. You time will not be compensated even at minimum wage. In 2008, when I attended a session with a licensed quilt appraiser, she said that a twin quilt was worth a minimum of $275, based on the costs of the materials alone. Materials have gone up, as we know. At this point, DH and I have decided that I will make auction and raffle quilts to benefit local charities and quilts for kids in out of home placements, but otherwise my quilts are for family and friends.
If you are doing this because you like the person, make sure she understands what the real costs are, whether or not you charge her that much.
Don't underestimate the importance of your work. I have given quilts to people newly diagnosed with cancer. 2 of the 3 are now 5 year survivors. One had been diagnosed as 98% terminal with brain cancer that had spread widely. Both credited the sense of love on holding the quilt as a large part of the cure.
