Hanging Art and Displays

I like to have mobiles or other hanging displays in the classroom. I put up permanent cup hooks, usually above each desk.

It's time-consuming and dangerous to climb up on chairs and desks to hang or change these displays. Teacher Opal Miller gave me this solution:

Take a 1x1 piece of wood and two yardsticks. Attach a yardstick to each side of the square piece of wood, with the ends extending beyond the end of the 1x1. To hang a mobile, put its string over the ends of both yardsticks. Lift it and loop the string over the cup hook. To take down a mobile, turn the yardsticks sideways and knock the string off the hook. With this device, students can safely change displays, saving you time.
