Flowers and sunshine herald the arrival of spring. To get into the spirit, start by stripping windows of heavy draperies. In their place, hang a single sheer cotton panel on a tension rod or a piece of bamboo (available from florists, who can cut it to measure). Then make up your bed with pale floral-print sheets or floral pillowcases paired with crisp white linens. Drape bedside tables with vintage floral tablecloths (they don't have to match) or white matelasse runners. Finally, add a potted plant or two (try a Reiger begonia, which will flower indoors if it gets enough sun), so you can wake up every morning to the bright green of spring.
