As seen in The Twilight Saga: New Moon...
I used worsted and a size 7 11' circular. You can do magic loop, two circs or DPNs as you would like!
Cast on in multiples of 6... 30, 36, or 42 stitches.
place a marker and join in a round
Work 15 rounds of 3x3 rib.
Work 20 rounds of stockinette
Starting on stitch one, turn and purl back to the last stitch before the marker.
Turn and knit back to the first stitch.
Work back and forth knitting one row and purling the next for 10 or so more rows, ending with a purl row (make sure you slip the first stitch in each row for a neater look.)
Join back in the round (i k2tog to get a tighter join... if you do this you will need to increase one stitch anywhere in the next round.)
knit one or two rounds.
Work 12 rows of 3x3 rib
