What are these? - If you've ever tried to use a table cloth outdoors on a breezy day, you probably know that these are table cloth clamps. These little gadgets easily clip over the edge of a picnic table and hold a table cloth in place. This gadget, and hundreds more like it, are made by Coghlan's, a Canadian company that has been making outdoor accessories for over 45 years. You can find Coghlan's products in most sporting goods stores.
