Hi.I;am kinda stuck on this part of the instructions from the pattern North Country Cotton Baby socks.It says"Using a new needle,pick up and knit8 sts along the otherside of the heel and continue knittingto the center of the heel sts(3 sts)(needle 3).There should now be 11 sts on needles 1 and 3 and 12 sts on needle 2.''What does this mean?.
That's the way you have to pick up stitches to make the sock in the round again. Here's a tutorial on sock making. The page I've linked to is the "picking up stitches for the gusset" page. See if this helps then you can come back with questions.
