I am glad to be at home since it´s rainy and grey outside! I have some tips for this weekend, and they are both indoors in case the weather decides to stay like this:
IJ Hallen (Saturday 15th and Sunday 16th) It´s a huge flea market that takes place in Amsterdam Noord, you have to take the ferry but then it´s a small walk. The entrance fee is 4.50€
And on Sunday you can find the Neighbourfood market on the Westergasfabriek with lots of yummy things to eat! Starts at 11.00 till 16.00.
They have a great blog with recipes, check it out here! makes me wanna go even more :)
