Yarn Store in Schwerin Germany

While walking towards Schwerin castle from the train station, saw this sign for a yarn store.  I've seen this done in other stores in Europe but when I worked at a yarn store in the US and yarn bombed the post outside the store, the mall management removed it right away.  Too bad.  It's a great way to advertise because I wouldn't have noticed the off the main street yarn store otherwise.  It actually was  a craft store, not much yarn but worth stopping by.
