For a perfectly square table you may be tempted to use four matching pieces for a perfectly symmetrical look. However you can get a more intriguing look by using two pieces or groups one in each corner. Try a tall vase or lantern in one corner with a stack of two or three books in the other (and an airy sculptural accent on top).
Using a vintage object for a coffee table adds a bit of history — a story — to a room and is one of my favorite things to do. Make sure the piece is stable and all the connections are secure. If you need to refinish the piece ask the vendor precisely what it’s made from as this will help in the refinishing process.
