English pattern is ready and available: I am offering the pattern for free and would be grateful in return if you could manage solving problems by yourself. Feel free to use the pattern as inspiration for your own modifications.

UPDATE: Start lace pattern (chart 1) in round 10, at the end you will have 42 stitches on the needles!

An US-knitter wrote this: You’ll want to start the lace when you have 38 stitches on the needle in order for the lace chart to line up! (the 10th row of the chart is 21 stitches long for top half)

In der 1. deutschen Fassung ist ein Fehler im Chart, die Korrektur ist im Update: Das Lochmuster beginnt in Runde 10, nicht danach!
