Once a month here in Germany there are some “Sperrmüll”, although I looked for it and there is no direct translation, is a day when garbage truck come and collect things that people signed up to throw away (big things, furniture, pieces, material,etc. that is not thrown away to the regular recycling bins). They ask to leave the stuff on a collection point (changeable, depending on the demand of the area) at least 24hrs before the collection day. When I first arrived to Germany, it was shocking all the stuff (specially on summer) that people throw away! This does not happen in Mexico (as far as I know, correct me if I’m wrong).
So every month I casually go for a walk around my neighbourhood to see what people doesn’t need anymore. You can even see stuff three days ahead. And really you can find so many things, in good conditions! There is people that already knows and arrive with a van to collect the stuff, probably the re-sell it or who knows what. We have collected many things from the “Sperrmüll”, i.e.: our bed side tables, a stool for our entrance hall, bookshelf, drawers… very useful and in great conditions, really! We saved a few euros: travelling to the nearest Ikea = 15kms (much of the furniture is bought there, convenient), time and money actually buying it.
But something that is very common to see are bed frames, which are very similar to the baby cribs rails. When searching for ideas to repurpose bed frames (I already have two, one as a shoe rack and the second still on its way to turned into a towel hanger), the bed frames I have are not precisely like the ones showing, so I searched instead for baby crib rails, and that looks more likely! So here are a few ideas to inspire you, all in one place, is a good combo I must say, enjoy!
