I'm really enjoying knitting this boomerang. I was inspired by Laura Nelkin's online class. This class describes how to customize common shapes or create a new piece by varying increases, decreases, yarn overs, etc. It's a super resource that I will use over and over. My boomerang shaped shawl will have a slight curve at the straight edge and opted to use m1s at the inner curve because I actually like the way that edge looks. And, I love the soft feel and drape of the yarn. I'm partial to anything alpaca!
