Before I forget, this was also started some time in August last year and finally got completed a couple weeks ago; happily residing in one of the drawers :) The yarn is organic cotton (color 41115 - Susan) and I very much enjoyed knitting it.
It is a difficult color to capture with the camera. The photos above are very close. It is like DMC 500. The picture below is to show the stitch pattern (double moss), does not reflect the right color. Neckline is crab stitch (crochet).
Update October 2015 ... The neckline is a beautiful crochet technique but not suitable for this sweater. I decided to change and am happier now :)
