This is a variegated yarn worked on the diagonal. Yep, I found the yarn in the clearance bin. It was a lot of fun to work with the colors and textures. http://www.craftsy.com/pattern/crocheting/outerwear/skylark-scarf/118777
This one I made wide with a twist when connected the two short edges to close the circle. I can wear it like a shrug or a scarf.

My version of a chunky V-stitch scarf with 3 buttons. Only I didn't use buttons. Lacing works too. No pattern.
