Worse than a bee in my bonnet

Well it's a good thing there were about 10 balls of denim yarn in the bag I picked up from the Knitting and Stitching Show.

Because, it's frustrating when the yarn on the left side of the picture magically becomes the yarn on the right side of the picture. Magic? Foul play? Bad Knitterly Karma?
Nope.
Styfoam, ye will be the bane of my existence.

(Luckily, I think I have enough yarn for my sweater in progress. *Crosses fingers*)
