Futuristic family Halloween costumes

Tip: Be resourceful: shop at thrift stores and dollar stores first to save money, then try vintage shops and hardware, costume and toy stores for more odds and ends.

Tip: Think about anything and everything: duct tape, knobs, nuts and bolts, bits of plastic, wire, cord, wood pieces, light bulbs, aluminum pans, plastic dishes, strainers, cooking gadgets, old sporting equipment, paint and craft supplies. But think lightweight—you don’t want to make the costumes too heavy to wear.

Tip: Silver spray paint is a great “space-maker.” Objects take on a completely futuristic look with a coat of silver spray paint. Also helpful to have on hand: a drill, nuts and bolts, 5-minute epoxy, adhesive removers, sand paper (to scuff plastics and metals before painting) and Velcro.
