Q: My carpeted floors squeak, so I'd like to screw the loose subfloor to the floor joists from above using one of those special screws with the snap-off heads. But how do I find the joists under the carpet?

The 18x24-in. carpet samples you often get from a carpet store have many uses: Lay them down in front of a workbench or washing machine as a floor cushion. Slice them up and tape the strips to the top of a sawhorse. Glue a piece to a step stool for a nonslip surface. Or use them in a car or truck as rugged floor mats.
