As long as the free table is available at meetings it is a good idea. To do it at your quilt show is not good especially if you have vendors at your show. The vendors at quilt shows are there to offer your members and attendees a variety of quality merchandise, when the guild uses the show for their own garage sale, or free merchandise it cuts in to any profit your vendors make. Most guild show members and attendees are not aware of the expenses vendors have in order to vend at their show. As a former vendor in order to vend at a show I figured it would cost me a thousand dollars in expenses before I made anything. And that did not include any replacement cost of items sold. Sorry if this sounds like a soap box, just offering a little perspective.
