Original pin from Hobby Lobby: Use our versatile river stones to update your favorite space. - I would skip the faux moss and faux flower and use it as a planter for a live plant on my back deck! Use any size rock for outdoor planters!
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.
