Done! My Vitamin D sweater, started in June 2012, is finally off the needles, and I've been sporting it around town. Since I wanted my cardigan to be longer than the pattern suggests, I knit 5 lower body radial rounds instead of 4.
The yarn is Lisa Souza BFL DK in the Forbidden City colorway. I purchased this at Stitches West 2012. Happily, this yarn softens up quite a bit after a good soak because part of the reason the cardigan sat around so much was that each time I tried it on, it was itchy. I lost my motivation because I hate wearing itchy wool! But, since my girlfriends have reinstated our weekly knit nights for 2013, I had to do something during that time other than eat cookies, cheese, and drink sparkling wine. So, I dragged the sweater with me. Some nights, I didn't knit a stitch, and then after about the 3rd week of dragging the sweater around, I really wanted it done. Two days later, the second sleeve was bound off and I was ready to soak it.
The most exciting part about finishing this sweater is that I no longer have a sweater's worth of yarn stashed away. Wheeeee! This makes me feel free! I have a few single skeins of yarn leftover from projects and some earmarked for socks, but besides that, my stash is teeny tiny. The anti-hoarder in me is rejoicing.
