Excellent! I feel in the company of great people!
Loukr, Freecycle really is that great. It's ettiquette (SP?) to offer something on your first go, then after that, you can ask for things or email people who have offered things. Try and give a good reason why you want something if you're emailing, not just say "I'll have it" as some people like to know their beloved but no longer accommodated thing is going to a good home or a worthy cause. They'll have sent ettiquette rules and guidance when you joined. But from personal experience - always keep appointments!
I furnished my studio through Freecycle, and it's opposite a car boot market site - 2 days a week!
For clothes - I don't have much apart from underwear and t-shirts that isn't second hand! Although sometimes I find out why it was given to the charity shop in the first place- itchy or unflattering! But you just have to wash it to get rid of that generic perfume smell that charity shops seem to infuse into their clothes - know what I mean?
Anyway, thanks for all your replies so far!
