Our little village held a mass garage sale last year. Lots of us opened our garages (or just set up stuff in the drive in front of the house) The organiser advertised it for the whole village and we paid him a small sum each, which went to the church roof repair fund. It wasn't tiring because we were at home and could makes endless cups of tea for ourselves and any 'customers'. Some people (including me) sold scones, cakes and refreshments as well as 'stuff', and we got to keep the takings for ourselves. What I liked was the chance to natter, and also (leaving my husband in charge of our things for a bit) going for a tour of the village myself and seeing what was on sale elsewhere. All in all it was absolutely magic. Got rid of unwanted clutter, met lots of nice folk, (they came from other villages too) and made a bit of money. Not to mention the church which gained from the donation.
