Cabled Tapered Headband

This pattern is based on the Calorimetry Headband at Knitty.com

We sell tapered cabled headbands at work and I figured I could probably make one. Here is the pattern!

Needles: size 10 circular
Yarn: Lamb's pride bulky (I used two worsted weights together to create the color combo)

Cable pattern will be made on the wrong side of your work. 
Cable pattern: 
Row 1: K4 
Row 2: P4 
Row 3: C4F (transfer two stitches to cable needle and set in front of work. Knit the next two stitches then Knit the two stitches from the cable needle) 
Row 4: P4 
note: I don’t make the cable pattern on the outermost corners of the headband because there are so few rows.
