Decided that if I was going to do airbrushing, I needed a spraybooth. As they cost a stupid amount of money, I built my own with the aid of my father-in-law (who's a genius on these matters).
In all, the whole booth cost me about £25 for the wood, a bathroom extractor fan, a kitchen lamp, some sockets and cabling. It's nice and sturdy and exhausts via a tube out the window. I also put handles on the sides as the top part can come off for storage (I saw another forum member's booth had handles and thought it was a great idea) and a small hook in the wall to hold the airbrush.
Here are some images:
