Ravelry: It's the Cerus scarf (free pattern) which uses linen stitch, but this one has a difference. The knitter used three balls of yarn. Two of one color and one of a different color. I like the dots.
Linen stitch tutorial - but it's really simple: Row 1: *k1, slip 1 w/yarn in front* repeat Row 2: *p1, slip 1w/yarn in back* repeat These 2 rows create the pattern, I love it especially with variegated yarns. mz
