SO cute! You could do the same thing for a little girl with mommy's heels and accessories.
If they are girls! I probably could do the same thing for boys just less pink and girly frills.
Homemade musical instruments: "Ankle Bells"...these are knit but you could easily do the same thing crocheted!
Yarn Wrapped Monogram.... could do the same thing with a tree...cut out and wrap in twine?
