This cardigan has been an odyssey. I decided in early 2007 that I had to have a U-neck, raglan, 3/4 sleeve cardigan, and promptly cast on in pea green. A year and much perseverance later, I had the world's ugliest sweater. I definitely learned from my mistakes! Though this is far from perfect (the neckline won't lay flat and I forgot to take my boobs into account), it's far better than my first attempt, and it was dirt cheap.
Here you can see what I'm talking about: the front barely closes. If I leave the top two buttons undone, it's much better.
You can see how the neckline tends to curl under in back.
I knit this in Caron Simply Soft from the top down on size 8 circulars. My favorite part is the buttons. You can't tell, but they're square, translucent, and glittery! They were a little expensive, but the woman running the checkout counter gave them to me for half off. :-)
If I could do it again, I'd shorten the sleeves a bit (or lengthen them) since they're a little awkward, place the raglans better, and be more careful picking up stitches for the neckline/button band.
