Translation: Pattern for sock heel
I'm knitting my first sock, my first time knitting in the round...
Can someone help me decipher the pattern for the heel? I understand that I have to knit half minus 2 of the total number of stitches (28, in my case), or 14 on the 1st needle and 14 on the 4th needle. But then the pattern says I should also work the edge stitches to facilitate picking up heel stitches. It's the edge stitches I'm uncertain about. The pattern says:
Edge st: Sl the last st of row with yarn in front, work the first st of the row as k through the back loop.
What does Sl mean? Slip?
