Since I’m a graphic designer I'm obviously into books and my favourite bookstore in Amsterdam is Boekie Woekie. This small shop is located in the Nine Streets and they sell nice and special publications that are often hard to find because they are self published or published by small press publishers. If you are into graphic design you should really check it out.
The city's biggest flea market is hosted the first weekend of each month in and around a gigantic warehouse in the industrial area of NDSM in Amsterdam Noord. I love to snuff around the hundreds of stalls to find unusual props. Taking the boat to cross the IJ and leaving the old centre behind is very refreshing. Make sure to also have a drink in Noorderlicht while the sun sets.
The fence around De Nederlandsche Bank on the Frederiksplein is a true optical experience. While passing the building, a rhythmic, dynamic pattern appears and disappears in the trellis of the fence. The figures on the sides of the rails were designed in 1992 by artist Peter Struycken, a pioneer in the area of environmental art and generating computer-program based image, light and colour compositions.
Candles, incense and fragrance oil to lighten up your place, this place carries tons of it. You might be greeted by the slightly unusual owner, sitting behind the counter smoking a cigarette. It's an authentic little store.
