Where to find small pieces of foam

[teejay]

I remember back when I was using broken ceiling tile for stratified rock on my old layout ........approached the Home Depot manager , told him that I was a model railroader and , crazy as it might seem to him , needed broken ceiling tile .....he took be to the warehouse area scrap bins and said " help yourself , take what you want " ! I made sure I shopped there afterwards when I needed supplies to finish the second bathroom .
