Floating Flower Tip - Most flowers float pretty well on their own until they start to pool with water and slowly sink. For a longer lasting centerpiece, use bubble wrap to make little skirts for your flowers.
Escondendo o cano da calha-Hide the downspout with a trellis. Hide your rain spout by transforming into a decorative climbing support for your favorite flowering climbing vine. I really like this idea and it looks great too.
