Try This: Plastic Jug Light Shade

Create a translucent window shade out of plastic jugs.

4. String the triangles together to a length appropriate to your window using closed “S” hooks. We used 3/4–inch zinc-plated hooks. The edge of the plastic will just be able to fit in where the “S” doesn’t close completely. Use a larger “S” hook for the topmost triangle and slide it onto a small dowel.
