Carpentry

 is a Skill that is unlocked by finishing the Carpentry quest, which involves giving 64 wool to the Carpenter, who will then reward you with the recipe for the Carpentry Table which allows you to build furniture which the Carpentry skill unlocks.

It is one of three "cosmetic" skills, which have content locked to players without a Rank. Players without a rank cannot increase past level 3 in the skill, and higher ranks apply a higher exp multiplier. As a "cosmetic" skill no important content or any stats require it to be leveled, and other than some small benefits it may provide (such as tabbed chests) it's purely decoration. The other cosmetic skills are Runecrafting and Social.

Much of the furniture that can be created with carpentry is purely cosmetic, although some of them are upgraded version of normal vanilla blocks (such as a large chest with 3 tabs)

You can gain experience in Carpentry by crafting things (including creating enchanted forms of resources).

Furniture
Carpentry is the main way to obtain furniture and is the main purpose of carpentry.

Carpentry EXP Multipliers
If you have different ranks on Hypixel, you will get more XP.
 * Normal: x1.0, Max level 3
 * x1.1
 * x1.25
 * x1.5
 * x2
 * x3

How to get Carpentry XP:
 * 1) Making enchanted resources like enchanted diamonds. (the rarer the item the more XP you get)
 * 2) You get experience proportional to how many items are required. It's most efficient to get items which tier up such as Perfect Armor, Griffin Upgrade Stones, etc.
 * 3) Making non-vanilla items. Some vanilla items will still give you carpentry XP while others won't. This is an intended feature.
