Round shapes and dark colours create a sense of calm. This glass vase from House Doctor in a classic dark green is a nice example. It is see-through thanks to the colour which has been spray painted onto the outer surface. Place it together with similar vases on a side table or as a centre piece with dried flowers or twigs on the dining table. An equally decorative option is to create a unique display with candle stands and other vases in similar earth tones to create a warm and inviting atmosphere.
