Ziggy With it Cowl

This one is for my crocheting lovelies! A mosaic crochet ziggy zaggy cowl pattern with post stitched ribbed edges. I personally fell in love with this cowl - it is so eye-catching.
Now, let's talk yarn - the yarn I used to work this up is called High Desert - a newbie from Knit Picks. This yarn is 100% American grown Shaniko Wool and comes in Worsted and Sport.
This yarn feeeeeeels so soft, the worsted actually feels like a dk weight. Love, love, love it! So I made a cowl with it! And I'll tell ya how here for free! So, grab yourself some of this yarn and when you have it in hand - come back here and get to making!
Notes: Cowl worked flat then seamed together. Pattern is a multiple of 8sts plus 2 sts. When changing colors, carry yarn up loosely along side.
