T loves circular tables. There is something about the equality of it all ... that conversation flows among everyone, not just between those who share sides. In Chicago, we purchased this 3/4 inch piece of circular glass (the diameter is 5'). I wish that I could say it was cheap, but I remember it being around $400. It is burly, though. Many kids have stood on it (without permission, of course). It has scratches of character. And I HAVE to wash the underside ... something I would otherwise ignore! We have had many bases - galvanized sawhorses, painted sawhorses, a twig table. Most recently we made the base out of an old wire spool that I got for free from a local utility company. We painted it grey (Benjamin Moore dark primer, actually). Then added quilting to the top and staple gunned leftover suzani fabric. And I can easily switch it up on a whim!
