Wool farming

Wool farming can be useful for many things including, but not limited to, paintings, beds, and banners. Wool is mostly used for decoration, but a bed can be one of the most useful items you can get and it is easily attainable from wool.

The Infinite Automatic Wool Machine
This machine provides you with infinite wool, and does not take many resources at all.

Construction


 * 1) Build a 1 by 2 dirt platform and surround it with a wall that is as high as you want made of glass blocks.
 * 2) Under the dirt blocks place two hoppers connected to a double chest.
 * 3) Build a staircase to the top of the wall and lead a sheep of any color into the container. After the sheep is trapped, put a glass roof onto the container.
 * 4) Knock out one of the glass blocks that are 1 block above the dirt platform and place a dispenser in its place, making sure the dispenser faces the sheep. Place a pair of shears in the dispenser.
 * 5) Connect the dispenser to a redstone clock so it shears the sheep every few seconds.

Why it Works

The dispenser will use the shears on the sheep as often as you made it happen with the redstone clock. The shears do not lose durability when the sheep has no wool. When the wool gets dropped, it is sent through hoppers to the double chest.
