Most pedestals come in three basic shapes: square, circular or rectangular. Which is right for your piece? Consider the shape of the artwork (especially its base), and also the part of the room the art will be displayed. Square bases often look best on square pedestals, and circular on circular. But there's always room for improvisation. Try cutting out the different shapes from newspaper or cardboard and set the under your artwork to help you visualize how each might look under your piece.
