Balls

Searching for "sock balls" - I found my way to this Adaptive Physical Education site from the Anchorage, Alaska school district. It's a bit sketchy, but the following list of "balls" is a good indication of how the spirit of fun can lead to an inventiveness that transcends physical and commercial limitations.

Balls

have a wide selection
yarn balls do not bounce or roll away easily, they can be caught by a strand of yarn
