I used aran weight (worsted weight) wool and 60cm 5mm circular needle.
Cast on 90 sts and join for working in the round.
rnd 1: *K3, P2 repeat from * around.
Repeat this round until desired length. I did 4 1/2" ish, enough to cover your neck.
Now you start working back and forth across the needles instead of around.
row 1: K2tog, k to 2 sts before end, SSK
row 2: p across
Repeat rows 1 and 2 until 2 sts are left, k2tog then pull yarn through.
Weave in ends.
The point on this cowl fits nicely into v-neck jumpers to keep your chest warm.
