I made this sweater using Creative Focus Chunky by Nashua. It was my first attempt at knitting something wearable and it turned out beautifully. There are quite a few increases/decreases to contend with so I wouldn't say it's easy, but it's still do-able and fun for a slightly advanced beginner who's knitted all the scarves she can handle :).
I just bought this yarn in Malachite for a sweater project. It's lovely but wow does it bleed color onto my fingers and bamboo needles! I understand now after doing some internet research that's common with hand-dyed blues and greens. Wish I'd have known that earlier because I'd have picked a different color.
