Your friend will likely be familiar with this notation, which is fairly standard (though not by any means universal). I think it means: knit 2 stitches, then knit the next stitch twice (incrementing the number in that row as result); knit 6 more then slip the last 3 stitches while holding the yarn in front.

Thank you!

Mouse over each abbreviation and you should see a tooltip. This specific row would mean "2 knit, Knit Front Back, 6 knit, with yarn in front 3 slip."

These are generally written as k2, k6, etc. -- is there a reason why you reversed them?

Oh, good point, I might swap them. I think you're right.

I sometimes print something like "8(K P)" where I think putting the number in front makes more sense. But yeah, I think if there are no parentheses, I should just print it as you suggest.

Thank you!

OK, I've adjusted the output accordingly (https://github.com/alefore/knit/commit/b08f1d1957acf7b37c2cf...).
