get (make or buy) some stitch markers (the kind that hang in a stitch, not on the needle) with numbers (baby braclet beads come in numbers, too)
then on the needle divide the stitches with simple markers
on the knitting hang the number markers..
1 is first needle(stitches) after Beginning of Round, #2 is usually instep, (and sometimes #3 is too) and then the last bunch of stitches before BOR (#4)
now, you have the stitches on 2 circ, but the stitch markers remind you where Needle 1 is, where Needle 2 is.. etc, and you can just follow the directions!
the # markers get moved up (closer to needles) as you work..
after a few socks, you won't need them!
