Handball knitting

I started this project in the beginning of December, because I needed some stocking stitch knitting to calm my nerves during Norway's matches in the European Handball Championship. Now I have to try to finish the Happiness knot before tonight's match against Denmark.

I like the pattern, it's Armenius, from The Inside Loop's winter issue 2008, by Kai Mistry. I'm using a different yarn, Juvel by Idena, which is thinner than suggested in the pattern. My tension is 21sts/10 cm, in the pattern 17sts/10 cm. Following instuctions for size M, this should fit a ten year old boy, if my calculations are right.
