Each year I donate a few quilts to my home town Bible camp annual quilt auction. They almost always bring in more than I had spent on materials, and part of that reason is becauseI buy materials at garage and estate sales, plus get fabric donated to me. They never bring enough to compensate for my time.
In addition, I occasionally do a special quilt with a friend at church, and it is donated to the church for a fundraiser or other purpose. This summer we are working on a quilt made from art work (on a bed sheet) done by young children during a mission trip that our teenagers went on. It is likely to be something displayed in the church youth room or perhaps given to the mission community. In the case of working with this friend, I don't care one bit whether or not or how much money might result from any of our quilts -- the privilege of working with this friend is all the satisfaction I need.
I make and donate quilts because I enjoy it. If I didn't give my quilts to the auction, I would be accumulating them and have a storage problem. I already make many charity quilts for places where they are given to recipients. My auction quilts are the ones I have spent more time on and often have challenge to them.
Each person had to look at his/her own situation and do what works for them.
