I'm going to say "ditto" to doing as you please with the quilt. If it was a raffle for a car, and you didn't drive, would you feel bad about selling it? Probably not, but with the quilt you might because friends worked on it. If those who worked on it would be "disappointed" it's their disappointment, not yours. The tickets were sold to benefit the guild; what happens to the quilt, or any other raffled item, should not be their concern.
