When counting rows, the cast on doesn't count right? When it says to "knit 12 rows", does that mean the 12th is the loops on the needle or the 12 completed rows (13th loops on needle)? Thanks
Right, the CO is a cast on, row one is the one you knit after that. The 12th row is the last completed row, not the one on your needles. I count the bumps on the WS in stockinette or ribbing.
