When you unbox a large item at your house (a new TV or kitchen appliance, for example) save one or two large slabs of cardboard before recycling the rest. Store the cardboard pieces behind your workbench or tuck them along a wall in your garage or workshop and you’ll have a disposable drop cloth at the ready for your next messy project.
Large pieces of cardboard are great for covering your workbench or floor when finishing furniture or working with messy glue or paint. They also come in very handy for DIY automotive tasks. A slab of cardboard is a bit more comfortable to lay on than the driveway when you have to scoot under a car, and it’ll catch any drips that may fall while you work.
