If you're interested in it, there's one guy I know of in Aus who's got a book and some videos online, can't vouch for his level of expertise but he seems to know the basics of sewing, lasting and the rest - goes by the name of Tim Skyrme, might be a decent starting point for you. There's also a forum called the crispin colloquy where some guys, mainly in the USA, talk over technical stuff.
It's a pretty deep subject though, there's a lot of steps and many distinct skills required for each stage so lots to learn. If you have any questions I'd be happy to give my opinion on what might help along the way so just feel free to ask.
Cool! I've seen a lot of his videos, but I didn't realise he was in Australia. I think I'll just keep chucking along and then go to a course over christmas or something. Thanks, I'll bear that in mind
