Gusset in sock, knit flat

Hey everyone! First off, I just have to say that I like knitting socks in the round a whole lot better than flat. But I guess that’s what you get for doing argyle… :inlove: My question is about the pattern, the area in question is red.

Place all sts on 1 needle for sole. P 1 row, k 1 row until [COLOR=red]37 (74) [/COLOR][COLOR=black][COLOR=red]rows[/COLOR] from where sts were picked up on sides of heel.[/COLOR]

[COLOR=black]I just don’t understand what the 74 is about… I’d appreciate any insight! [/COLOR]

Whoops, figured it out. :slight_smile:
