Banner

Banners or Flags are tall decorative blocks, featuring a field that is highly customizable using dyes.

Usage
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 pattern can be washed off using a cauldron.

Patterns
A banner may have up to six patterns, which are overlaid with the last-crafted on top.

Any color banner can be used, the color will just be overlayed with the pattern. White banners with black and occasionally red patterns are shown here for simplicity.

Copying
Banners can be copied with a blank banner to make multiple identical banners.

As a fuel
Banners can be used as a source of fuel, smelting 1.5 items per banner.

Trivia

 * A banner is, visually, 2 blocks high and 1 block wide, but only uses the bottom block (or top block when placed on a wall); this allows another block to be placed directly above (or below) it.
 * A banner is, 20 pixels on the bottom, and 40 pixels on the side.
 * Banners sway in the wind.
 * However, banners lie still when in the nether.
 * With 16 blank banners, 38 patterns of 16 colors each (608 uniquely-colored patterns), and 0 to 6 patterns per banner, the number of uniquely crafted banners is 16 × ( 6080 + 6081 + 6082 + 6083 + 6084 + 6085 + 6086 ) ≈ 809 quadrillion (809,573,616,779,945,488). The number of visually distinct flags is smaller, because one or more patterns may completely cover other patterns, or the entire banner, or be duplicated due to the symmetric set of patterns (e.g. field Or (yellow) + per pale azure (blue) = field azure + per pale Or inverted).
 * Although it is impossible to add more than 6 patterns to a banner through crafting, it can be done using commands. When hovered over such a banner in an inventory, only the six bottommost patterns are displayed. By using this method, the number of unique banners is approximately 24 trigintillion (one trigintillion is a one (1) followed by 93 zeroes).
 * The Mojang Logo is called "Thing" ingame, which could be considered an alternate translation for mojäng. If you use Google Translate, it translates to "thingamabob".
 * Banners can be used to block the flow of liquids like signs.
 * If a banner is placed on a wall, It can be knocked off by a piston. However, if the banner is simply placed on the ground in front of a piston it will act like a block of Obsidian and prevent the piston from activating altogether.
 * Banner textures are located in \assets\minecraft\textures\entity\banner.
 * There are 34 monochrome textures, each containing all 6 sides of the banner.
 * The texture of the back side is mirrored texture of the front side.
 * Textures are inverted, that's because they're not used as textures, instead they act as masks for re-colored base texture, base.png. That means white is visible, while black is transparent.
 * Also, the banner textures are first to use antialiasing.
