Here's my parts list:
plastic storage bin
2 desk lamps
Make sure the bin is translucent, not transparent, or opaque. This is for proper diffusion of the light. This can be hard to find. Mine has transparent middles near the handles, but it still works fine. Alternately you could line a transparent bin with white tissue paper to make it translucent, or use diffusers on your lights.
I used tape to keep the construction paper in place.
I set this up on the edge of my kitchen table so I could use a regular size tripod and not have to buy one of those mini tripods.
When you're done, everything can be stored in the box!
