I would like to find used (but not cracked) terracotta plant pots - the sort of thing someone clearing out a shed might find and just maybe take to a car boot instead of the tip - anyone have any idea where such a car boot might exist - Googling brings up stuff that hasn't been updated since 2008 or so and I don't know what's still going!
Any ideas of other sources or even where there might be old chimney pots? House clearance places might also have them. I'll buy the cake at the next meet in return for suggestions!
