Mercerias en Espana

I realize that yarn shops may be difficult to find in touristy locales in Europe, but I've finally found two - one in Barcelona and the other in Madrid (this one was closed). I ended up buying German yarn at a merceria in Barcelona - oh well, I was just happy that I found a shop after searching high and low in the Netherlands and in Paris. I also found out from dad's housekeeper that "knitting" in Dutch is "brine" (at least it sounds like it - most likely not how it's spelled) :)
