For each cassette chandelier, you'll need gloves, translucent epoxy for plastics, cassette tapes, an egg carton (or something for holding epoxy as you work), cotton swabs, fishing line, ruler, light bulb, light socket and wire (Ikea has them), scissors and tweezers. Not shown, but needed: White duct tape.
On a clean surface, position tapes into a square. Next, apply epoxy (following manufacturer's directions) to the two short sides of each tape and let dry in the square formation.
Build the tiers as shown above, using epoxy to hold the cassettes in place. Let dry completely.
Put fishing line (about 2 feet) through the two holes of the two opposing tapes on a tier. Then, attach fishing line to the light wire with white duct tape. Repeat with all tiers. To finish, you can pull the tape from the inside of each cassette with tweezers and cut with scissors (for a fringed effect as seen in the first photo) or leave as-is. Alicia also recommends using a colored bulb in the light socket for extra flair.
