Here are some basic materials that I used:
black cartolina (preferably, Matte)
For the light diffuser, I used a white fabric. At first, I tried using bond paper but found fabric as a better option. I bought mine at the market. I asked the saleslady for the cheapest fabric so she gave me "Gina Selk" or Gina Silk
I created 3 box-type parts like this one: two for the sides and one for the top light. It holds the light bulb and the fabric light diffuser.
I don't have step-by-step images of how I created this. I was too busy in building this light box that I forgot that I'll post this in my blog in the future!
here's the finished product
