Minecraft wiki entry for Armor_farming, associated text: Once you have all of the materials is is time to put them all together in an anvil. First place the piece of armor in the first slot of the anvil. Next, place the enchanted book in the second slot of the anvil, and in the third slot there will appear the piece of armor you will get after enchanting. The anvil will also show you how many levels it will cost you to put them together. Do not enchant yet. You are going to want to have all of the enchantments lined up and ready to enchant. Also, to get the most enchantments on a piece of armor, or any tool, you must put the enchantments with the higher number first. For example, if you were putting a unbreaking III enchantment on the armor, but you also wanted to put protection IV on the armor, you should put the protection IV first so you can fit more enchantments on tools and armor.
