Your friend already told the group that you would probably not keep it. If you sell it, maybe donate some of the proceeds back to the guild to help cover some of the cost for the next raffle quilt? You mention having some health issues? I would guess tat any $$$ from selling the quilt may help you with your expenses.
Frankly, you won the quilt fairly. You are not obligated to report back to the guild any plans you have for the quilt.
Congratulations!!! By the way. I won a quilt a few years ago! What a thrill that was! I rarely win door prizes.....seems like the same people do every time.
