Make a sheep farm. Basically get some sheep (at least 2) in an enclosure - simplest is a two block deep area that they can't jump out of (Place a ladder one block off the floor for yourself to get out) - and feed them wheat every 5 minutes to breed up a large population. Then you can shear them for wool.

Tip: if you want a specific color of wool, dye the sheep that color and their wool will always regrow in that color till you dye them another color.
