Yarn: I’m using worsted weight, Rowan Cork, probably about 400 yds, more or less.
Needles: 7US, but remember I’m LOOSE (cough, cough). You might go 8 or 9US.
Gauge: Eh, whatever. It’s a scarf.

Cast on 33 stitches.
R1 (right side) : k1 p1, across.
R2-4: k1 p1, across.
R5: (k1 p1) 3 times, k4, p2, k9, p2, k4, (p1 k1) 3 times.
R6: (k1 p1) 3 times, k1, p3, k2, p9, k2, p3, k1, (p1 k1), 3 times.
R7: Repeat R5

R8 and all following wrong side rows: (k1 p1) 3 times, k1, p3, k2, p9, k2, p3, k1, (p1 k1), 3 times.
R9: (k1 p1) 3 times, k4, p2, put the first 3 sts on cable needle, hold at front, k the next 3 sts, then k the 3 sts from cable needle, k3, p2, k4, (p1 k1) 3 times.
R11: (k1 p1) 3 times, k4, p2, k9, p2, k4, (p1 k1) 3 times.
R13: (k1 p1) 3 times, k4, p2, k3, put the first 3 sts on cable needle and hold at back, k the next 3 sts, then k the 3 sts from cable needle, p2, k4, (p1 k1) 3 times.
R15: Repeat R11.

Repeat rows 8-15 until you’re happy with the length. If it won’t go around your neck once, it might be too short. If you could ride a horse and rope a steer with it, it might be too long. Otherwise, you’re good to go. End with 4 rows of k1 p1 across, bind off. Add fringe if you’re that fancy.

Suggestion number one: This would be a good way to learn how to cable. It's easy. Swear.
Suggestion number two: Try cabling without a needle (the fastest way to go). Wendy, of course, has the best instructions HERE.

Enjoy!
