A couple people asked me for the "pattern" for the headband. I just made it up but here it is. (In the photo, you will notice the cables changing directions. I decided that looked silly so the following pattern only has the cables going in one direction.)
Measure the circumference of your head where the headband will sit. The finished headband will be 3" smaller than that.
For the Malabrigo, I think I used size 6 needles. I am making another one now out of some Peru Luxury DK (merino, alpaca, silk) and am using size 4 needles. I'm a loose knitter.
C6=Place 3 stitches on cable needle. Move to front. K3 off left knitting needle. K3 off cable needle.
Cast on 18 stitches.
Row 1: K3, P3, K6, P3, K3
Row 2: K6, P6, K6
Row 3: K3, P3, K6, P3, K3
Row 4: K6, P6, K6
Row 5: K3, P3, K6, P3, K3
Row 6: K6, P6, K6
Row 7: K3, P3, C6, P3, K3
Row 8: K6, P6, K6
Knit in pattern until headband is 3" shorter than the circumference of your head.
Sew two ends together.
