I'm an intermediate knitter, I'd guess. I'd like to try this scarf pattern, but I can't seem to find an explanation for the "cb4" that appears in the pattern. Here's a link:
I'm assuming it's a cabling thing, but it doesn't make sense to me given the surrounding stitches (plus I've never cable-knit before, though I'm game to try it). Also, if anyone has instructions for the I-cord cast-on described here, I'd appreciate it, since the link on that page is broken.
