Dry Needle Felting
Needle felting is a popular fiber arts craft conducted without the use of water. Special barbed felting needles are used by the artist as a sculpting tool. A needle is used to sculpt the wool fiber. The barbs catch the scales on the fiber and push them through the layers of wool tangling them and binding them together. Fine details can be achieved using this technique and it is popular for 3D felted work.
