I just made mine bigger .. 12 100 watt light bulbs instead of 8 .. gives me more light plus since it is bigger the opening in the center is large enough for me to move around .. not much but a little .. and I can easily pull back for good 3/4 body shots.
For the background I have a yellow matte board I picked up at hobby lobby for $4 sitting on a easle. There is also a single 100 watt household light bulb directly behind her head aimed at the background .. which gives the gradient effect.
I don't have it setup at home. It's setup in a corner down at the studio. In all the entire setup only takes up a few sq ft of space. It's a nice cheap addition for your studio if you have a corner that is not being utilized. I will try to remember to take some shots of it.
