Take the broken plastic frame and reinforce both sides of the crack with staple pins. Melt the staple pins into the plastic using a soldering iron until they are fully embedded. The frame is securely joined and ready to use again.

Take the broken chair with a cracked seating area. Drill several small holes along both sides of the damaged section.

Cut small pieces of strong copper wire and insert them through the holes. Tighten the wires from the back, then melt the wire ends into the plastic with a soldering iron.
