I belong to 3 guilds - one very small, one very large, and one somewhere in the middle. In the very large guild we just line up when it's time for show and tell, show the quilt and say something about it. No pictures are taken. In the very small one we go around the room asking if there is any show and tell and if we have something we take it up front and show it. One of the ladies has recently started taking pictures for the web site, but they're nothing formal. I'm not sure exactly how show and tell is handled in the medium sized guild since I just joined last month, but I didn't notice anything formal. I don't really see the need for anything "organized" regarding show and tell. Just do what comes naturally. I wish that in the really big guild we had more time to see all the quilts up close, but there are just too many people for that.
