It didn't take long to finish the first Mad Budgie sock after I had negotiated the heel.
I decided to work 5 repeats of the grid pattern up the leg as the original 4 seemed a bit short. And 5 is a better number somehow!
I stuck to the original design and worked the picot cuff as written.
I am really pleased to have been able to copy the sock as it appears in the book, despite my lack of German. It was really not hard at all! If anyone else is swithering over whether or not to buy the book in its original language, I would say "Go for it!". If you have other sock knitting books and a smattering of experience you will be fine!
