The other day I read a review of a book about things from days gone by. One of the things they recalled was a rubber band ball.
I remembered them too and have a plethora of elastics so I got started. Richard took over when he saw that my elastic skills sucked.
All you do is build a series of rubber bands on top of a golf ball. And then keep adding. And if you need an elastic, just pick one off! Not so crazy.
