This is just a simple, K1-P1 rib scarf -- yet it is reversible (as the purl stitches "hide" and allow the knit stitches to appear as if it's knit stitched on both sides) and so soft using Lion Brand's Cotton Ease. This one is for Lego-Maniac and took just over a skein each of "snow" and "charcoal" making this scarf approx. 45". For an adult version, I'd add 2 more repeats of the 15-row stripes and end with the snow, to make it about 60". No fringe so this can stay nice and elegant!
