There are plenty of tutorials to make reclaimed wood or stump coffee tables. Most of them just require for you to get a piece of wood, sand the ends, and call it a day...somewhat negating the need for a tutorial at all. But! This one takes it a bit further by adding an painted gradient or ombre effect for a more finished look.
Whimsey Box made this cool table by removing the bark from the stump and applying a few coats of paint. I love that you don't really need crazy equipment to do this. A few basic tools will do, along with some paint and some sheets to cover your floor if you're like me and have to work inside.
