The photos below are of various needle felted, handmade from raw wool, and knitted and then washed vigorously (fulled) felted items. Needle felting is great when you are frustrated or angry. You have to be very careful, though! Stabbing the tar out of the wool, then slipping and impaling yourself is very painful. Those needles are extremely sharp. I use a "kick-board" that kids use in swimming pools for my felting base when needle felting. it is thick enough to protect you from being stabbed while felting the wool.
Most of these items I have blogged about previously more in depth.
