I call myself the styrofoam queen. I get so much styrofoam I started years ago of trying to figure out what to do with it besides trashing it and filling our overload landfills. Every TV, Appliance and electronics I purchase have so much of the stuff around some weeks it would take me 4 garbage bags to take to the curb.
I cover them with stones and ceramic tile.
This was the last one I made and posted instructions of how I made it.
