Old Shale Scarf

I've been just crafting away lately.  And since I make so many scarves I figured I better learn how to make some patterns.  My friend Lisa told me about this site called Ravelry.com where you can get patterns for knitting and crocheting.  I haven't made it to Jennie caliber yet so no crocheting for me.  But I found quite a few patterns in want to try to knit.  Here is my first one.  What do you think??
