As you stripe, do a 3/3 cable.
For the left armwarmer, use a 3CF (sl 3 sts to cable needle, hold in front, k next 3 sts ,sl 3 sts off of the cable needle and k them).
Work this cable on Round 11 (MC) of the stripe pattern, and then again on Round 2 (MC) of the stripe pattern.
Author's Note: This means that the row before you change to CC and the row after you change back to MC will be cabled.
Do 5 repeats of cable and stripe pattern, or until the armwarmer is the length you want from just below your thumb to your wrist.
As you continue this pattern for the 6th time, increase the thumb gusset in the purl "seam" stitch that's ended every round using the following pattern.
Round 1: P in front and back of purl stitch.
