Neckwarmer Pattern

A few of my knitting friends have asked for the pattern for the neckwarmer I made a while back, so here it is. I didn't write it down as I was making it, so I'm partially going on my memory here. My apologies if my memory is a little fuzzy.

Yarn: about half a skein of Misti Alpaca Chunky (a full skein is 108 yards)
Needles: Size 13 circular needle (um, 12 or 16 inches long, I think--something short)

CO 40 stitches. Place marker and join to work in the round.
Work K2, P2 ribbing for 4 inches.

On next round increase stitches and start cables as follows: *K into the back of the second stitch on left-hand needle then K first stitch and slide both stitches off the needle, P2, K1 front and back, K1, P2. Repeat from * around.

Round 1: *K2, P2, K3, P2. Repeat from * around.
Round 2: *K2, P2, K3, P2. Repeat from * around.
Round 3: *K into the back of the second stitch on left-hand needle then K first stitch and slide both stitches off the needle, P2, K3, P2. Repeat from * around.
Repeat these 3 rounds for about 7 inches. Bind off and weave in ends.
