Works on multiples of two stitches.
Row 1: *Yarn over, knit two. Pass the yarn over over both knit stitches. Repeat from * across.
Row 2: Purl.
Repeat these two rows for pattern.
Making a yarn over at the beginning of the row can be a little tricky. Just drape the yarn over the empty needle and make sure you've wrapped the yarn around the needle before working the first knit stitch.
