I succeded after all. Here's a couple of christmas ball done, just in time before the visit from Jydske Vestkysten (Danish newpaper) today. A little bit of knitted christmas is needed for such a visit 
I've knit it after this free knitting pattern: Christmas Balls. And of course they have already found their place in the window.
My daughter has already ordered 200 pieces for next years christmas tree
The only thing missing now is snow...
