I have been knitting all this time. And here's the result. It's perfect. The pattern is well-written, easy to follow and great for movie&knit evenings. It'll easily become his favourite sweater, so I'm already browsing through Ravelry and looking for other men sweater patterns. With no luck so far.
Details: knit on 3.5mm (US4) circulars. Yeah, I must be a totally loose knitter because I usually have to take several sizes smaller needles. I swatched (!) with 4.5mm and 4mm circulars and did not like the look of it at all. Had I gone with the larger needles, the sweater wouldn't be as snug, I guess. But he likes it this way & I do too.
The yarn that I used is Cascade 220 Heathers and the colour is sea blue (#4005). I used only 5,5 skeins out of 7, so I still have some left for a scarf or something. I love this colour.
Other news knitwise: I've knit and frogged the back section of my Phildar cardi. I'll try to modify the pattern a bit and knit the whole thing in the round. I'll let you know how that goes.
