How can I repair scratches in wood furniture?

Home Depot sells a 3 furniture crayon package. I just filled my gouge with the

crayon let stand for a few days, then went over the scratch with a bit of varnish using a toothpick so I wouldn’t spread varnish over the smooth wood. Can hardly tell where the scratch was.

If you can’t find the crayons for your color of wood, then there’s colored “putty sticks” that are like a filled Tootsie Roll.

Cut off a section of the putty stick & kneed the epoxy filling in your hand. It can be sanded easily when finished.

If they aren't deep you can rub out surface scratches in your wood furniture with a paste made of mineral oil and pumice (available in powder form at hardware and paint stores). Use extra-fine-grade steel wool to rub the mixture into the scratched area. Then wipe it off and buff with a dry cloth.
