OK, now I'm about to start on the thumb section of my second pair of mittens using this pattern
, and I'm still unclear about the line that states: "Next round: Knit to marker, place next 12 sts on a small stitch holder, cast on 2 sts,
knit to end of round.
The part that is confusing me is "cast on 2 stitches"
-- the rest I understand. Why do you suppose I need to cast on 2 stitches? I mean, what purpose does this serve?
I'm going to do the thumbs using DPNs (instead of sewing), for what it's worth.
