Okay, so here are the supplies I used:
2 1" wide strips of sheet metal (the diameter of the shade you need will determine the length, for best results, make it the diameter of your boob light, or just slightly bigger-not much though)
4 1" wide 7" long strips of sheet metal
2 white poster boards (the sturdier the better)
Clear packing tape
Step one: Determine the size you want for the shade. I found that two poster boards put together made the perfect diameter for me. And 12" high is what I needed. So, I got the poster board, laid it on the ground and taped the middles together creating a super long piece. I then taped the sheet metal strips along the bottom, and one along a 12" mark I created on the poster board.
Step two: Next is to create the shape. So, make the two short edges meet and tape them up.
For me, I was able to just hang this light, and somewhat bend the metal inwards to hold. You can probably do this for mounted boob lights and have the strips go between the metal and the ceiling.
You can still see the boob light if you look underneath it, but at least this conceals it from a distance :)
