Handwarmer pattern, as promised

You need: a bit less than 200 yds or 100g of worsted weight yarn. 1 skein of Brown Sheep Cotton Fleece, Patons Classic Wool, Cascade 220, or that sort of thing will do nicely. Also, a set of 5 DPNs in size 6 or 7, whatever gets you 5 stitches to the inch in stockinette stitch. The mitts are made on 4 DPNs; use the fifth for cabling, or use a cable needle if you prefer.

Abbreviations:
C4B = slip 2 st to DPN and hold in back. K2 from left needle, then K2 from DPN
C4F = slip 2 st to DPN and hold in front. K2 from left needle, then K2 from DPN
C1B = slip 1 st to DPN and hold in back. K2 from left needle, then P1 from DPN
C2F = slip 2 st to DPN and hold in front. P1 from left needle, then K2 from DPN
M1 = make one stitch using backward loop cast-on
PM = place marker

Instructions between * are for both mitts. The only difference between L and R mitts is the thumb placement. The thumbs are worked in gussets, which are indicated by brackets [ ].

*CO 45 stitches and distribute as follows: Needle 1 has 15 stitches, needle 2 has 16 stitches, needle 3 has 14 stitches.

Needle 1: (P1 K4) 3 times every round
Needle 2: follow cable pattern (above)
Needle 3: (K4 P1) twice, K4 every round

Work 36 rounds (Rounds 1-24 of cable, then 1-12 again).
Work one more round knitting all knit stitches and purling all purl stitches.*

Right handwarmer:
Work first 36 rounds as indicated between * above.
Next round (this round 1 of thumb gusset):
Needle 1: (P1 K4) twice, PM [M1, P1, M1] PM, K4
Needles 2 and 3 continue as before.
Work until thumb gusset is complete; there should be 15 stitches between markers.
Next round:
Needle 1: (P1 K4) twice, slip gusset stitches onto spare yarn, M1 (this replaces the P stitch in the gusset), K4
Needles 2 and 3: continue in established pattern.
Work until you have completed round 12 of cable. Cast off in pattern.

Left handwarmer:
Work first 36 rounds as indicated between * above.
Next round:
Needles 1 and 2: continue in established pattern.
Needle 3: K4, PM [M1, P1, M1] PM, K4, P1, K4
Work until thumb gusset is complete; there should be 15 stitches between markers.
Next round:
Needles 1 and 2: continue in established pattern.
Needle 3: K4, slip gusset stitches onto spare yarn, M1 (this replaces the P stitch in the gusset), K4, P1, K4
Work until you have completed round 12 of cable. Cast off in pattern.

Complete thumb:
Remove waste yarn from thumb gusset stitches and arrange on 3 DPNs. Follow rib pattern as established around thumb, picking up 3 stitches at join on inside of thumb. These 3 stitches will all be knit.
Work 1 round even.
On next round, work in established rib pattern, decreasing two stitches on inside of thumb.
Work 3 rounds even.
