On the evenings when my brain gets too fuddled for math (sick kids, lack of sleep), I've been entertaining myself with the Dulaan sweater:
I'm keeping this one dead simple - straight sides, dropped sleeves. I am steeking the armholes, but when I write up the pattern, I will include the option of flat knitting the upper portion of the sweater. This little pullover is a great blank canvas for experimenting and playing - the stranded knitting is necessary for warmth and wind resistance, but the actual patterns can be as simple or complex as your heart desires. I opted for two colours, because I am sick to death of weaving in ends, but you could easily work in different colours or even yarns, as long as they were wool and of similar gauge. Think functional swatch.
