I used 3 skeins of Vanna's Choice in Oatmeal with a K hook. This scarf is worked lengthwise to give the appearance of a ribbed knit scarf.
Row 1: hdc in 2nd ch from hook, hdc in every st across
Row 2: ch 1, turn, FPhdc in every st across
Rep row 2 until the scarf is the desired width. Fasten off, and weave in all ends.
