Turns out this one is even easier to make than I expected.
Then you need a plastic inflatable ball which can be found at the dollar store and some glue.
I prefer a stiff fabric glue, but imagine any glue might work.

Add an LED hanging lightbulb and voila, creative lighting is yours.
This DIY lighting idea will look great in just about any room.
And the patterns this light casts on the walls?
