Exterior Decorations
Instead of throwing out old clothes, says Eisenberg, use them to make a scarecrow. Take a shirt and pair of pants and stuff them with newspaper or plastic bags. (Just make sure they won't blow away!) Support the scarecrow with a broomstick pushed into the ground. For the head, glue spare buttons onto a brown paper bag to make eyes, a mouth, and ears and tie the bag onto the body. Top off your scary creation with an old hat.

To bring out the boo, says Eisenberg, spook houseguests with ghosts made from old, white sheets or holey socks. Cut the sheets into circles or ovals of various sizes. Place stuffing (such as newspaper, plastic bags, or leftover material from the sheets) in the center of each round to make the ghost's head and tie with ribbon or string. For a sock ghost, stuff one sock into the toe of another and tie with string. Then decorate your ghosts with old buttons, ribbons, and other forgotten items sourced from the back of your craft drawers. Hang the ghosts at varying lengths from the ceiling or stoop.

Use Forest Stewardship Council–certified lumber, which is derived from a responsibly managed source, sustainable plywood, or reclaimed/repurposed wood to make spooky build-your-own decorations, such as tombstones for the yard, says Paul Novack, director of sustainability for Green Depot, an environmentally friendly building-materials supplier. Novack also recommends using repurposed household items, such as old, rundown furniture, when creating a haunted house, and tin buckets for apple bobbing.

Novack suggests setting the witchy mood with "eerie lighting that uses energy-efficient or compact fluorescent black lightbulbs." You can scare some up at Blacklight.com. Homeowners might also consider buying energy-saving LED (light-emitting diode) lights to illuminate the lawn for trick-or-treaters. "Energy Star–qualified LEDs provide a dazzling light display while saving money for you," says Karen Villeneuve, director of the New York State Energy Research and Development Authority's (NYSERDA) Residential Efficiency and Affordability Program (REAP). NYSERDA is a public-benefit corporation committed to helping New Yorkers find safe, economical, and efficient ways to solve the nation's energy and environmental problems.

"The LED bulb is made up of tiny light sources the size of the head of a pin, but what they lack in size, they make up for in brilliance," she says. "LEDs come in Halloween orange and black, as well as many other colors; are 90 percent more efficient; last ten times longer than incandescent light strings; and give off very little heat."
