how to make a light box

Looking back at my previous posts with the jewellery shots, it struck me that the light box I had made perhaps wasn't ideal for obtaining really good photos of the objects. Perhaps the light was in the wrong position or maybe the background paper was too pink as the shots have a lot of red in them. So I decided to see if I could find a better example of a homemade light box. I came across the following website: http://digital-photography-school.com/blog/how-to-make-a-inexpensive-light-tent/ which has a lot of positive feedback so I'm going to give it a go and will report back in due course with some, hopefully, improved jewellery shots.
