Transsiberian hat pattern

Here's my pattern for the Transsiberian hat, as promised. If anyone actually makes this, please let me know! Also, I briefly looked through the pattern for mistakes, but I wouldn't be a bit surprised if I missed something, so if you catch an error, let me know right away (in comments) and I'll fix it.

I should figure out how to get this pattern onto Ravelry...




Materials:
A bit under 100g (maybe 150 yds or so) worsted weight yarn such as Lamb's Pride Worsted or Cascade 220.
size 7 (4.5mm) 16" circular needles
size 8 (5mm) 16" circular needles
size 8 DPNs, set of 5
stitch marker
cable needle

Size: About 20" around, fits an average woman's head (assuming my head is average). To change sizes, try a tighter or looser gauge, or add an extra purl stitch between cables. This is a free pattern, so I'm not doing any extra math unless someone specifically requests it!

Gauge: 4.5 stitches = 1" on size 8 needles in st st. I have no idea what my gauge in the pattern stitch is...but the hat fits me, so I guess it's all right!

T3F = slip 2 st to CN and hold in front, p1 from left needle, k2 from CN
T3B = slip 1 st to CN and hold in back, k2 from left needle, p1 from CN
C5B = slip 3 st to CN and hold in back, k2 from left needle, k3 from CN
C6B = slip 3 st to CN and hold in back of work, k3 from left needle, k3 from CN


Diamond cable pattern (from the new Harmony Guide, see p. 193 if you want the chart):
All even numbered rounds 2-16: k all k stitches and p all p stitches
R1: p2, C3B, p1, C3F, p2
R3: p1, C3B, p1, k1, p1, C3F, p1
R5: C3B, p1 [k1, p1] twice, C3F
R7: k2, p1, [k1, p1] 3 times, k2
R9: T3F, p1 [k1, p1] twice, T3B
R11: p1, T3F, p1, k1, p1, T3B, p1
R13: p2, T3F, p1, T3B, p2
R15: p3, C5B, p3

Other cable:
Rounds 1-3: knit
Round 4: C6B

To make hat:
With size 7 circular needles, CO 101 stitches. Join into a round. K2tog, p1, then work 1x1 (k1, p1) rib for 3" or desired length of brim.

Switch to size 8 circular needles.
Next round: [k5, inc 1, p4, C3B, p1, C3F, p4] 5 times. You should have 105 stitches.
Next round: [k6, p4, k3, p1, k3, p4] 5 times.

These two rounds establish the cable pattern with two purl stitches separating each cable. Continue in this manner (your next round will be round 3 of each cable pattern) until two repeats of the diamond cable are completed - 32 rounds total.

Decrease thusly, switching to size 8 DPNs when necessary:
[k2tog, k4, p6, k5, p6] 5 times
[k2tog, k3, p6] until end of round
[k2tog, k2, p6] until end of round
[k2tog, k1, p6] until end of round
[k2tog, p6] until end of round
[k2tog, p5] until end of round
[k2tog, p4] until end of round
[k2tog, p3] until end of round

Cut yarn and pull through remaining stitches. Hide ends. Wash and block if desired.

You've got yourself a hat!
