Minecraft is a game that many people enjoy playing, and one of the ways to do so is by unlocking new items and costumes. One such costume is the Lumberjack shirt, which can be unlocked by finding a piece of lumber in the world and putting it into a crafting table. To unlock the Lumberjack shirt, you will need to find a piece of lumber that is at least two blocks long and has a block of wood on top. Once you have found this piece of lumber, put it into a crafting table and select the Lumberjack shirt option. You will then be able to wear this costume in-game.
