It did get ready in time for the wool festival at Backnang, and now I have finished translating the instructions into English.
The German version is already available in the online shop - it should be downloadable for free, if there should be any trouble, please let me know. Before I post the English version to the shop, though, I'd like to have a native speaker give it the once-over to catch any stupid bits of Denglish (which tends to happen when translating, unfortunately).
Any volunteers?
