When creating socks, gloves or anything requiring that you make two or more identical pieces do you:
(a) count rounds as you knit using a stitch counter or tick marks on paper?
(b) work until the size is approximately right, then count how many rounds you've done?
(c) use a measuring tape and not worry that you may be off by a round or two?
(d) hold the finished piece next to the one you're working on, again not worrying about having exactly the same number of rounds?
(e) some other method?
My sense of perfectionism demands (a) or (b), but I wonder if maybe I should just relax a little and go for substantially similar rather than identical. What's your approach?
