Spell out "I Love you" by recycling paper shopping bags into luminaries. Use a stencil kit from the hardware store and, tracing the letters onto several bags, spell out whatever phrase your heart desires. Cut out the letters with an X-Acto knife and fill the bags with clean kitty litter, pebbles or rocks to weigh them down. Light them up with clean-burning soy candles or, a safer bet, rechargeable "candles" from Candela (vessel.com).
