Wool

Wool is a block derived from sheep that can be dyed 16 different colors. Wool blocks are weak, flammable, and do not offer much resistance against explosions.

As of the Beta 1.2 update, white, light gray, gray, and black wool can be obtained naturally by shearing sheep. White wool can also be created by combining 9 pieces of string together, although harvesting wool from sheep is considered a better use of the player's time. You can shear sheep from afar with a fishing rod without hurting them, making wool easier to harvest. Sheep are shorn in one hit regardless of what it equipped, however placed wool is more durable. It is quick to remove, however using a sword will speed up the removal slightly, at the cost of 2 uses.

History
Wool was added for the creation of paintings, carpeting, colorful structures, and in-game pixel art. Wool is also a suitable material for docks, as wool blocks will stop boats and absorb some impact from the collisions in a manner similar to Soul Sand.

In Creative Classic mode, wool blocks were known as cloth blocks that came in a set of 16 colours, although the palette was slightly different from the one available in Beta. Three shades of gray were added in Classic 0.0.20a.

Except for white cloth, colored cloth blocks were unobtainable during Classic's Survival Test and Indev unless they were pre-placed into the map file. They were completely removed from the code in Infdev. Placing these blocks on the map would cause the game client to crash, since the blocks no longer existed.

When colored wool was introduced again in Beta 1.2, cloth blocks were renamed wool blocks.

Trivia

 * Before leather was added, wool was used to craft leather armor.
 * When destroying wool, white wool debris is seen despite what color the dyed wool is.
 * It is recommended not to use string to make wool, as wool is easily obtainable but string is harder to obtain as it is only dropped by Spiders and found in Dungeons.
 * You will get more colored wool with one dye if you use it to color sheep and then hit them, causing the sheep to drop 1-3 wool blocks instead of just crafting one colored wool per dye.
 * The naturally occurring colors on sheep are black, white, light grey and grey.
