I think you'll find most of us quilt for pleasure. We give away quilts as gifts, donate quilts for worthy causes and occasionally keep a quilt for ourselves. This question comes up once in a while with a newby and it you go to the search box at the top right corner of the page and type in "selling your quilts" you will see many threads that deal with this subject.

I love Molly Sparkles and this is a great article/spreadsheet if you are thinking of selling your craft items:

I don't sell my quilts, it's my hobby and passion and selling would ruin that. I had a friend offer me $200 if I would make her a queen size, hand quilted quilt. That $200 wouldn't cover the cost of material. She got mad when I tried to explain the cost and said "they sell quilts at Sears for $100". Under duress I made a quilt for a family member. I told her to pay me what she could afford I got 1/3 of the cost of materials. She makes very good money and I was stupid for not giving a price up front.
Good luck with your endeavor!
