I have made it!
I have finished the my first Niebling project last night. It's a Niebling Oak doily. The pattern is from old german Anna Magazine (August 1985).
I knit it in mercerize cotton 330m/50g on 2.5mm needles.
I start doily two weeks ago and knitted it almost every everning. I'm very happy with the result!
You can see the doily here before pinned it.
