I would agree about completed quilts, however, having been the featured quilter at our last show, I totally understand the pressure and do't feel it would be tacky at all. My only advice is something I forgot and wished I had done and that was to have a book or register for people to sign and leave their comments. After a few weeks, you forget who stopped by and what nice things they said. It would be great to have a lasting memento of that weekend.
