I've used the blue foam, and like it quite a bit. 
I walked past a crafts section at the department store this afternoon and noticed sheets of various colored felt, including white. They're cheap, less than a buck. So, I picked one up and thought I'd try it as a cart fill replacement. But I apparently left it in my shopping cart.
Has anyone tried felt as a filler? Or, would it be just like the stock filler and no benefit, I wonder.
