To make a wall using Canadian Tables, simply turn a six or eight foot long folding table on it's end, extend the leg as a support and let it stand alone. Add as many as you need to get a wall of a suitable size. As more and more proceedings some in, you can continue to add tables. Almost every conference facility has these kinds of folding tables, but almost none of them have ever been used this way.
By the way, this technique is called "Canadian Tables" because the first time I saw it used was in Alaska in April 2002 when Michael Herman pressed several six foot tables into service this way. Our agenda/proceedings wall became so large that we actually built it clear across one end of the facility and around the corners and down the sidewalls. Eventually the room began to look like an ice hockey rink, prompting myself and fellow Canadian Judi Richardson, and and an Alaskan hockey player to begin playing an impromptu game of hockey with a puck shaped stone I had with me.
Hence, Canadian tables. *

...and it took me a while, but that is now obviously a canadian flag above. <grin>
