I also have to say I agree, youir daughter just doesn't "get it" although I understand where you are both comming from.
I make and give most of mine away. Because I love quilting I make small quilts and donate them to charity organizations and in recent times I decided to make a larger quilt and have donated this to be used as a raffle prize to raise money for the cancer association.
I make them because I love doing so. While I haven't found the need to do so at this time I would try selling them for a reasonable price to cover the cost of materials if I thought it was becoming an issue having them piling up in my store room.
