Try This: Lampshade Made From Plastic Bags

See plastic bags in a whole new light.

Lay two or more sheets of white bag so they overlap by a couple inches, creating a one-layer base that’s 14 by 36 inches. Stack pieces until base is three layers deep. Cover with parchment and iron from center outward so plastic fuses—30 to 60 seconds. Let cool. Add a fourth layer and iron so finished “fabric” is four layers thick. Flip and iron other side. If fabric is not fully laminated, iron again.
