Carpet

Carpets are thin blocks used for decoration. They are the same size as pressure plates. They are useful if you want a carpeted floor without using wool as the material. They have no collision, which will allow a person to walk over it without elevating 1/16th of a block, similar to how thin snow and lily pads work. Despite their nice look, carpets are very inefficient building materials, as crafting 1 carpet consumes 2 blocks of wool. The waste is evident when carpeting large homes. For example: a 20x20 room uses 400 wool for a wool block floor, but would use 800 wool if you were to use carpets instead.

Usage
Carpets must be placed on solid blocks, and cannot be placed freely or be free-floating in the world.

Carpets can be pushed and pulled by pistons/sticky pistons, but will pop off if pushed onto a non-solid block, or over a hole.

You can craft them in different colors by placing 2 blocks of wool of your desired color next to each other. This means that you do not have to use a crafting table to make them.

Carpets can not be crafted with two differently colored wool blocks.
