So far I've found only one--and it is completely soft and wonderful. I decided to make it into a scarf!
Thus, the Sweater-to-Scarf (or, more accurately, cowl) tutorial was born.
Step two: Zigzag stitch (or serge) around the hem so your scarf won't unravel.

Step three: Grab some thread the same color as your cowl and blind hem this edge up, just like you would hem your favorite pair of pants
Step four: Wear!!
(p.s. I love my rainbow crochet chevron afghan!)
