I finished the baby cardigan last night. It still needs blocking (in a bad way!) and buttons, but otherwise it's all done. I'm still not thrilled with how the sleeves attached, but even with fiddling that's as good as it got:
I'm hoping some blocking will help them out. It ended up bigger than I expected (Debbie Bliss' sizes do run large) so it may be for the fall rather than when he's a newborn.
Here is the yarn and the start of a swatch (warmups) for my knitting olympics project. It's an acrylic yarn but really nice and soft.
