- When initially crafted, a banner will be the color of wool that the player used to craft it.
- Banners can only be crafted if all wool blocks are the same color.
A banner holds a flag that can take on many different appearances. There are 16 colored blank flags, and numerous patterns each available in 16 colors. A flag can feature up to 6 different patterns. Banners, much like signs, can be placed both on the ground, facing different directions, and on walls. They can also be placed in item frames, where they simply appear as their item model. A layer of patterns can be washed off using a cauldron, like dyed leather armor. They can also add patterns to shields. Banners can also be used as fuel in furnaces, smelting 1.5 items per banner.
A banner may have up to six patterns which are overlaid with the last-crafted on top. The location of the banner in shaped recipes does not matter as long as the dyes are in the exact location specified. Players can also overlay these patterns on each other.
- With 16 blank banners, 38 patterns of 16 colors each (608 uniquely-colored patterns), and 0 to 6 patterns per banner, players can create approximately 809 quadrillion uniquely crafted banners.
- Although it is impossible to add more than 6 patterns to a banner via crafting, up to 16 can be added using commands.
- Banners are available in the Pocket Edition as of update 1.2.
- Banners naturally generate in End cities as of update 1.9.
- On Console Editions, there is a separate crafting section for banners which is located underneath the firework crafting section if classic crafting is turned off.
- The texture of the back side is mirrored texture of the front side.
- A player can make a "Mojang" banner with an enchanted apple, a banner and a colored dye of their choice.
- As of update 1.13, banners can be seen on a map, making them a useful tool for labeling important places.
- A Minecraft world can only contain 400 banners in Java Edition, but on consoles, even less are permitted.
