The light box was made out of a cardboard box, tissue paper, posterboard, and 2 desk lamps on either side with daylight bulbs. I think I may need one on the top as well, but I was pleased with the results.
It's always good to post a photo of the "Thing" that you would like critiqued. I'd like to see how you made your homemade softbox along with the photo, otherwise it's difficult to critique.
