TUNISIAN CROCHET WITH MULTI-COLORED YARN.
I used a multi-color, thin yarn.  Afghan hook is used.   Cast on 24 stitches and continue your basic Tunisian stitch.   Make it a bit wider than your neck, so you can pull over your head.  Sew ends together with yarn needle.   You can wear three ways. #1 (up over neck)

#2 (folded over)

close-up of stitches (one side) , the other side looks "puffy."

#3 (hood)
