The Penelope Infinity Scarf is knit with two strands of yarn using the brioche knitting technique. I recommend using grey (as shown), black, or white as Color A to help offset and compliment your main color choice, B.

The second technique this scarf uses is the long cast-on here you are casting on the length of he scarf instead of the width.

The first several rounds are slightly awkward to knit, but it does get easier. You begin to really see the patter after about 5 rounds.
