No matter how basic the accommodations, a vase of fresh flowers will brighten things. The Miracle Vase, made of watertight PVC, starts out as a flat rectangular plastic pouch but morphs into a full-fledged vase when you pry apart the opening at the top and pour in warm water. The warm water softens the PVC, making it malleable. Slide your hand inside and you can mold the container into a variety of shapes. After use, empty the vase, refill with warm water, and flatten for storage. Vases are available in large (131⁄2 inches tall), medium (8 inches tall) or small (41⁄2 inches tall). An eight-piece set with four large and four medium vases costs $23.59; set of 10 small vases is $9.43. Info: www.miraclevase.com.
