A wire hanger. It cannot be a partially metal hanger made substantially of wood or plastic. A large, flat piece of cardboard. The tape of your choosing. Marking tape may be the easiest to work with; duct tape would certainly make the hoop durable. Markers or paint. Scissors. String (optional).
Try to make sure the relative scare of the hoop and backboard seem reasonable. For comparative purposes, an NBA backboard is 6 feet wide, while the basket opening is 18 inches (1. 5 feet). That means the basket width is 1/4 (or 25%) as wide.
You can tape along the front perimeter of the backboard and extend the tape onto the wall to secure it. Alternatively, you can make tape hoops (by attaching a single piece of tape to itself, end-to-end with the sticky side out) and use these to attach the backboard to the selected surface.
Scissors. Paper (best if it is somewhat rigid). Tape
The tip of the triangle or pyramid from earlier is now usually considered the top. As you fold the tips together you may note how easily they form a basket that opens wider toward the top.
