Yarn Bombing in Madrid

I saw many yarn stores in Lisbon and Madrid but they are typically small and carry Katia or Pingouin yarn which are available in the US and cheaper here too.  Although they have a lot of fabric stores that carry notions, laces, buttons etc that are much more extensive than anything at Joanns.  There are a bunch of them near the Lisbon Design and Fashion Museum.

As I was walking near Plaza Mayor in Spain and saw these street posts.

They are in front of a yarn shop, definitely good advertisement.  There was a class or knitting group inside so I didn't stay since I really didn't plan to buy any yarn.
