Also why do they start with Row 5? Row 1 is where you knit around after casting on, Row 2 is increase row (that I don’t know how to do), Row 3 is ??? and Row 4???
I was thinking that if you increase again on row 4 then when you increase on Row 5 you won’t have the 20 stitches they say. I guess I would ignore the Row numbers and do as Ingrid says. Knit a round, increase a round.
