I can't give you a statistical answer, but for the Brits in Adelaide I should think curtain making would be great as every house seems to be steeped in old fashioned net curtains - which personally I hate - and too short or too long curtains. A UK friend of mine has just ordered some curtains to be sent over from Next as she says she can't find a decent pair, ie M&S off the shelf variety, anywhere. Certainly if we weren't renting I'd want someone to make some. Shops are quite specialist here, they don't seem to do this kind of thing in dept stores, that I've seen anyway. Good luck.
