Yes, by all means bring along any leather you have gathered for your own use, or to share/sell to others or whatever.
Tim, sofa road-kill material is great. There's so much you can do with it. Bring it along by all means. Don't worry about tools though. Your wife can play around with my tools then decide which will be most useful for what she fancies getting into. I'll let everyone know where they can buy their own tools, or what substitutes are available.
Going by the number of people doing the course this year, I'm going to have to go and spend a couple hundred more quid on more leather - just to make sure we have enough to go round.
I'm really looking forward to this year's moot, with the Victorian Safari at Naughty Corner, and the Game of Thrones at Scot's Corner, it's going to be fantastic. So if you never met me before, and see me prancing round in my safari jacket and pith helmet, or in my saxon kirtle, don't worry, I'm not the local nutter on the loose.
