Groupings can be accomplished through the use of many items, such as glass, metals, colors, heights, and any combination of these elements. In those places where you would normally think on a smaller, less noticeable scale, try a set of taller, more robust candles like pillar candles. Place the tallest candle in back, a shorter candle near it, and then place a mid-sized candle along side the pair. This offers depth and an added sense of elegance. These can be displayed with the cylinder vases shown or the regular round glass holders.
