CARRY ON: For the past couple years, everyone's been lugging around those 99-cent reusable shopping bags. They're huge, they're strong, they're eco-friendly... they're ugly. Here's a cuter way to carry your organic, locally grown and preservative-free food: Envirosax Reuseable Bags ($8.50 each). The waterproof, lightweight bags come in five floral and geometric prints, and hold the equivalent of two supermarket plastic bags. GET IT: Greater Goods, 1626 U St. N.W. or online.
