I'm not up to this point yet, but I figured I'd start researching in advance for a change (what a concept, right?). I've watched a couple of different tutorials on Fisherman's rib, and it doesn't seem like it'd be terribly difficult. (I do the tricky part of it by accident all the time!) But all of the videos I've found have one thing in common: they're all knit flat. The only thing that doesn't quite compute is that when you're knitting flat and turn the work over, you continue the same pattern (p1, k1b) which -- I assume -- is the result of the even number of CO stitches making the last (k1b) stitch on the "RS" a p1 when you flip it over to the "WS (if such a thing can be said to exist in a reversible fabric). Since you're never turning the work over in the round, do you have to adjust the CO so the count is an odd number, or am I just overthinking things and you just horse on with the same stitch until you're done?
Also, how would the decreases work once you get to the crown shaping? I've done increases
(3x3) ribbing before, but I can't recall ever merging a knit and a purl in a decrease. It just don't seem natcherul.
