How to get felt up.

So with felting.. basically you have a pile of wool, sheep, goat, rabbit:-) alpaca, monkey...what have you.. you add warm water and soap and then begin to manipulate it by tapping or hitting(pounding if you've had that kind of day) slowly the wool binds to itself and you have felt.. there are many gadgets.. wooden spoons, felting needles what ever. I was mainly interested in 3d shapes. nests,squares, balls. flowers...
