But it's a good thing I did. I'm making a Shedir hat for my grandmother-in-law, and this sucker is fiddly and awkward. If I'd left it any later to cast on, it certainly wouldn't be done in time for Christmas. But it is very, very pretty, and I love the yarn. It is incredibly soft and pleasant to touch.
And I'm teaching myself to cable without a cable needle, since using a cable needle for one-stitch cables is just masochistic. It's going quite well so far.
I've also discovered that DK-weight yarn and 3.25mm needles seem to be my ideal combination. Very comfortable to stitch.
