Bigger $3.00 Light box

I'm currently building another cheap lightbox. So far the materials I bought include

• White posterboard $1.00
  
• black posterboard $1.00
  
• white foam core (for light reflector) $1.00 on sale usually $2.00
  
• Tissue paper (for light diffusion) $1.00
  
• Box free from World market $0.00

I'll take some progress pictures showing how I did it and how to use these materials. If this project doesn't fail catastrophically I'll post some pictures taken with this one. It should let me take pictures of slightly larger items than the shoebox version.

Please keep reading.
