The guild I belong to was getting way out of hand; some people were showing 7-10 items each. So, what they decided to do is place all the charity quilts in the back of the meeting room; they were hung over a coat rack and you could see most of each one. They then designated the "show and tell" for other items with no limit on them. I find it much more enjoyable since they switched to this method. Too many of them were looking too much alike and the time for our speaker was being infringed on.
