Ok, so, this is my first time attempting an infants sweater. Or any sweater for that matter. Row 3 says to k1, (k1, yo, k1) into next st, *sl 1, (k1, yo, k1) into next st; rep from * to last st, k1. Ok, so what does (k1, yo, k1) mean? why is it in parentheses? and I've never seen "into next st" before in instructions. Does that have any special meaning? THEN. The next row says to k3 tog tbl. When you tbl, do you enter the stitches like a purl but from the back? I'm terrible with diagrams but thats what the photo looked like to me. I think thats all I needed to know. Thank you to whomever can answer this for me!
