Ok, so, I am doing a Citron, like everybody else:
There are scores of them on ravelry, here, and here is the free pattern, but this was the one that made me want to do one myself.
I resisted a good long time, but now I kind of see why everyone is doing it. It is a very pretty pattern AND it uses only (about) one 100 gram skein. Who does not have a single (mm, yes, one, lol) skein of something pretty lying around just waiting to become a ruffled neck-warmer? I had a lovely ball of Crazy Zauberball in the colour U-Boot, that just never wanted to become a pair of socks. So behold, my (not yet finished) Citron.
By the way citron is lemon in Swedish.
