This isn’t exactly the yo-yo animal ornament Eleanore was looking for, but Noreen of Hankering for Yarn has come up with a yarn bear wearing a yo-yo vest.  She also shows a photo of a yo-yo chain that her daughter made.  This decorates the piano with Teddy sitting on the keyboard.
Noreen is from Canada and I live in the United States.  It’s interesting how we both have a fascination for the yo-yo’s of the quilting world and have made them with our daughters.
