Carpet

Carpets are thin blocks which are mainly used for decoration

Obtaining
Carpets can be mined using any tool, or without a tool. Unlike wool, carpets are not destroyed quicker when using shears.

Pocket Edition
In the Pocket Edition, carpets replaces the pressure plates of the tables in villages.

Usage
Carpets are the same thickness as pressure plates. They have a negligible hitbox, allowing a person to walk over them without elevating $1/16$ of a block. This is similar to how pressure plates work, although you cannot fall through a carpet. Unlike pressure plates, carpets cover the entire square they are placed on.

Listed below are many uses for carpets.
 * Carpets are useful for decoration if you want a carpeted floor without using wool blocks as the material. They can also be helpful when carpeting upstairs rooms without the ceiling of the next floor down being partially made of wool.
 * Carpets must be placed on a block, and cannot be placed freely or be free-floating in the world. However, they can be placed on "non-full" blocks, hiding tripwire, redstone, slabs, or other carpets below it.
 * Carpets can be pushed and pulled by pistons/sticky pistons, but will pop off if pushed onto a hole or pulled downwards.
 * Carpets can break falling sand and gravel.
 * Carpets do not prevent mobs from spawning. (It has not yet been tested if they spawn on carpets placed on blocks otherwise unspawnable on.)
 * Carpets placed above, or around, mushrooms growing naturally under trees will break the mushrooms if the mushroom is in a high light level, but will not break the carpet, leaving a floating carpet.
 * Carpets can also be used to hide blocks below it. For example, carpets can be placed on chests, thereby creating "hidden" storages.
 * Carpets can be placed on fences and walls allowing you to climb over them.
 * Carpets can be placed over water so that it can be walked on but still allow crops to be saturated and prevent items from falling into the water when crops are harvested. They will drop if the water beneath is removed, or if water (or lava) washes over them. Walking on carpet, placed on top of a water block also makes no footstep sound.
 * Mob AI's do not register carpet as a block they can walk on. This proves very useful in anti-mob passage ways. By placing the carpet above a block with no physical substance, like a sign, mobs don't register the carpet as something they can walk on, and provided a hole is underneath, the mobs will see just the hole and won't enter. This won't protect from a spider's jump attack, as it does not calculate height while doing this attack.
 * The same trick can be used for horse stables. By riding the horse onto the carpet, it thinks it's on a hole and won't move
 * Carpets will block the effects of book shelves when placed around an enchantment table
 * Carpet is an opaque block, however, it does not decrease light going through it.

Trivia

 * When you place blocks on it, those appear a block above the carpet — like other partial blocks, carpets "claim" their entire block.
 * This means undead mobs like zombies burn underneath it in the daylight.
 * If the player sprints across carpet, the particle effects are those of the blocks that are directly below it.
 * If the player puts a carpet on top of a bed and then sleeps in it, it will appear as if the player is underneath a blanket.
 * If you place carpet next to a block such as wooden planks, if you walk on the very edge of the block, over the carpet, you will hear the wool footfall sound.
 * Carpets will retain qualities from some blocks they are placed on top of such as Ice (Slippery).
 * Carpets do not have their own texture, rather they borrow from the texture(s) of wool.
 * Carpets seem to not appear in your hand. They are in fact there, but they are too low down to appear on the screen.
 * In consequence, when in third person view, the carpet is noticeably detached from the player's hand.
 * Water blocks with carpet placed over them will still turn to ice in "Winter" biomes.
 * Carpets can absorb a large amount of a creeper's explosive force.
