How do I choose and set a default skin for my items?

The skin selection button is located on the main lobby screen, to the right of your character. Tap it to open the skin menu. Choose a category (Weapons, Armor, or Building Items), then pick an item and select a skin. Set it as default — this skin becomes your "favorite" and will be automatically applied whenever you craft that item, pick one up from the ground or a chest, or join a server (for starter items like the hatchet and torch). You must own the skin to set it as default.
