I first heard about it from Passing Down Crazy's blog about her beginning it. I went and looked at it and was sucked in. There is also a Ravelry group, Advents Calender Scarf 2010 if you want to have a look around.
A some-what blocked out view.
This is the stitch for day 1.
Day 2, I don't think my nupps stood out very well so I planned to do them differently in the future.
Day 3, I think this stitch was also in the Shetland Pi KAL (which I will one day finish). :)
