Shelf Liner's great for keeping things from slipping around in cupboards and drawers, but you can really use it anywhere in the house -- like for keeping stubborn cutting boards from sliding around on your counter.
Shelf liners are usually meant to stay in one place, but they work so darn well for gripping your slippery items, there's no reason you can't keep a few sheets around for more mobile uses. The Los Angeles Times explains:
Next time you're out, stop by a hardware or home supply store and pick up a roll of shelf/drawer liner. The foam or rubber liners are perfect for keeping your board from sliding all over the counter as you try to chop. They're washable, dry quickly and can easily be stored (they take up almost no room when folded), ready to go when needed. What I love most about them is you can cut them to size.
In a pinch, they say, a damp paper towel or kitchen towel will do the job too, but it's hard to beat the effectiveness of a few cheap sheets of shelf liner.
