Woocutting requires a lot of patience and concentration!
You can find the "Woodcutting" skill in the "Normal" tab on the "Skill" interface. Then when you are on the woodcutting page choose the recipe on the left side. Then in the lower right part of the page, select the quantity to be produced. If you have enough materials in your backpack, press "Craft" to begin work! However, you need to be near Carpentry Tools to do this. you can learn woodcrafting recipes from a woodcutting instructor.
