My best friend had this happen recently. Her quilt was put into an auction directly after all the sporting memorabilia. She was very disappointed as was I for her. She had been told it was to be raffled. The school she donated it to would have made a lot more money if they had raffled it. A lot of the sports gear went for huge amounts but the men were buying with their emotions.
I believe people are quite happy to buy raffle tickets for a few dollars but baulk at spending big money for a quilt. Her quilt wasn't displayed properly either . It was folded to fit on the table and was carried around to show the audience still folded in a square. Very disappointing all round.
