How to get wool
You can get wool by shearing sheep, killing sheep, or crafting it out of string.

Automatic sheep shearing design
Dispensers can shear sheep if their hitbox is in the block in front of the dispenser.

How to build an automatic wool farm

 * 1) Place down a dispenser facing horizontally.
 * 2) Lay down grass blocks 1 block lower and one block in front of the dispenser.
 * 3) Build a pen out of glass(preferably the color of the sheep).
 * 4) Lure a sheep inside.
 * 5) Put an observer underneath the dispenser facing at the grass block to power the dispenser.
 * 6) Put a shear into the dispenser.
 * 7) Place minecarts with hoppers underneath the grass to collect the items.
 * 8) Make a room full of chests that the minecarts bring the wool into.
