Favorite German Yarn?

Hello all,
I’m in Germany for two weeks and of course I found a yarn shop already haha.
Does anyone have any recommendations of yarns to buy in Germany that are hard to find in the US?
Any suggestions/past experience is greatly appreciated! :slight_smile:

(I am in Freiburg im Breisgau, Germany in case anyone happens to have visited)

My friend just returned from Germany and bought me a skein of Rohrspatz Wollmeise (Iron and Wool).It also has the name Twin and Nobody is Perfect on the label. I haven’t used it yet but maybe you could check it out.
