PS - the title adds so much to the image. Also, reading your bio, I used to be an avid knitter for many years. Gave it up when I started running a number of years ago, but I have a deep devotion to the hobby, which is so rich and complex on many levels. :)
@rosiekerr thanks for the comments - I've enjoyed viewing your work as well! I've picked up running too and my knitting has slipped as a result. I wasn't very active on 365 for a spell in there, but have been so rejuvenated recently. All things in their time.
So many batteries -- So creative! I know you must have worked to get the visual balance in there. I like how the occasional negative on the 9v batteries adds visual interest.
