Sea Glass and Stones is a reversible cowl knit in one piece out of 3 colors of worsted weight yarn. You will need approximately 150 yards of color A, and 115 yards of color B and 100 yards of color C. Doing extra repeats as some knitters have done will require more yardage. One side is highly textured and the other is smooth, providing interest and contrast. Using the smaller needle as directed at the beginning and end of the pattern prevents the edges from flaring out, but if you prefer stretchy edge, use the larger needle throughout.
