The picture is one that i took using my setup.
Step 1: Backdrop.
I wanted a more permanent, but yet still portable solution. It also needed to be cheap. I bought a load of PVC pipe and fittings for about £20. I then got into my lego mindset and assembled it into a frame like shape. I'm sure you can use your imaginations to create a stable design.
I then got a big piece of white fabric, this cost me about £3.
I sewed a pipe sized loop at the top off the piece of fabric, to loop it over the top of the frame.
