If you're a designer, chances are that you sometimes or often find yourself drawing one iteration of a design over the next on layers and layers of paper. It can help to have a light table for this purpose, but there's one more option for those of us in small homes without room for such a uni-tasking piece of furniture:
Try using a glass desk or dining, side, or coffee table (if you like working on the floor). When you need a light table, simply place a lamp under the table's surface. It works really well and simply uses two decor items you'll be happy to use in your home even when you're not working.
