Light Box on a budget

I'm a Project Engineer by day, and a crafter by night. I would LOVE to share pictures of my latest creations, but I can't seem to find me enough quality lighting to take a good picture at night. Daytime is not an option because I work during the best outdoor hours.

The camera I have is a Rebel XTi. Her name is LuLu. She's great, unfortunately her flash is not. I've never been a fan of the flash, its too harsh and it tends to wash out the color. SO. I am on a mission to build my own light box. I googled "homemade light box" and was amazed at all the different options out there. I think I might try a hybrid of stuff that I saw online. The dorky part of me is all ramped up to get started! Lets hope that I'm motivated enough to finish it.
