I really wish I could help. But it's more complex than I can manage. The way things are phrased makes it difficult to decipher with all the knitting abbreviations mixed in. And they must be using abbreviations I'm not familiar with. Plus I've come across a couple works I can't even get an online translator to translate. It's simply beyond me.
Why don't you find a German teacher at a local high school or college and see if they can help? You could provide them with a list of common knitting terms in English and their abbreviations, which might give them what they need to translate it for you. Or they might offer it as extra credit for one of their students.
I'm sorry I couldn't be more help. Good luck!
