Some cloth examples.
Cloth was added on June 20th, 2009, as of update 0.0.20a. Cloth is a block meant to represent colors in the color spectrum, intended to aid in the creation of Pixel Art. Currently, there are thirteen colors, not including black, white, and gray.
Cloth can be crafted in indev and infdev into the lowest grade armor. It was previously possible to craft cloth armor in alpha, but as of the addition of cows in version 1.0.8, the lowest tier of armor is now made from leather instead. Cloth is gathered by hitting sheep.
Properties
Cloth is not affected by gravity, and will not fall if blocks below them are removed, it does not allow light to pass though it. Cloth is flammable.
