If you mean the garage sale like selling useless shit in front of your house? Then no, we don't do that. Ppl save their crappy stuff and sell it at a 'vlooienmarkt'. Lot's of folk do that at the Queen's b-day in Amsterdam.
Beautiful idea here. I see a lot of time intensive labor but it would be a good project to try and sell in an art fair. Do you have garage sales in Holland, Grim?
