I've finished my knitting, this is the result. I'm very happy with it. The idea comes from one of Nina Sagulin's books. Talking about ideas - take a look at this one, lace and ice, if it only was a little bit colder here I would certainly try it.
If you like to make snowflakes but doesn't want to have paper scraps all over, this is a good place :) Thanks for the link Camilla.
