You should check and see if there are any auctions near you. We have a wonderful antique auction near me and my friend has snagged some of the coolest rugs for as little as a 200.00. I had no idea the auction existed until she told me. Thought I would share. Here is one of her many various rugs. They are original and come from turkey, India, Bali etc. Super cool.

I suppose that adding extensions to the legs cannot hurt anything. If you decide it looks terrible, then you can try again. So... - Remove the top first. It should be screwed to the aprons from underneath from your picture. Store the top in some safe place to avoid dinging it as you work. - Choose a profile for the extension by drawing it on paper or cardboard stock. were it me, I'd go to the extent of drawing the whole leg, then cutting it out so my wife could ok the exact shape. No surprises. Surprises are bad. - Drill the legs and the extensions for a dowel insert. I'd go with at least a 1/2 inch dowel. 1 1/2 inches is deep enough. You can get packaged dowels for this from a local home center or by mail order. Make sure the dowel is just a bit shorter than the total hole depth. Too long of a dowel is bad. ;-) Drilling the table legs is best done with a drill press to make sure the holes are vertical. If no drill press, then do it carefully with a hand drill. Its easy to make a mistake here, so I'd try to find a friend with a drill press if possible. - Shape the extensions as planned. Test fit on the table legs. Make sure you are happy with how it looks now. - Sand and finish the extensions. Shellac might be a good choice of finish. - Test fit again. Put it together. Make sure you are happy before gluing. Use a woodworker's glue when done. Its best to finish before gluing, as its easiest to clean off a spot of glue after the finish is applied. You don't need too much glue anyway. If after some time you are unhappy with the result, then find a local group of woodworkers. In the Rochester NY area, its the RWS. See the attached link. They have a furniture maker's SIG. I'd bet you could find someone who would love to help out as long as you provided the materials and were willing to do part of the work.

It is a great start to a room, you have good taste. Do post to the Home Decorating Forum of Garden Web, they are truly the best.

If you don't really use the coffee table then how about an ottoman with a tray on it? Then the people on the couch portion have a place to put their feet up. I have a long, narrow ottoman in front of my couch. It was a place filler while I searched for a coffee table I liked. We got so used to putting our feet up when watching a movie that I never got that coffee table. Mine has a flip up top for storage. I keep a wooden tray in there and when we entertain and need a spot for drinks then I pop the tray on top.
