Cardboard & Styrofoam
What does everybody use their cardboard and styrofoam for? I use small cardboard boxes for organizing drawers, etc,---also break them down and use it in the garden to kill weeds, and I add some to my compost. Also plan to use some for pictures.
Styrofoam (is this misspelled) chunks I put in the bottom of heavy planters (some people put theirs in a bag first) and for mailings.
What's some other good uses?
