The needlecraft of felting uses wool felt to make three-dimensional creations. Felt is a thick, soft cloth, giving the resulting creations a highly textured look and feel.
There are two types of felting: needle and wet. Needle felting involves the agitation of wool by barbed needles, which causes the fibers to "felt" and bond together. Wet felting, on the other hand, uses soap and water to interlock the fibers.
Felting is one of the oldest textile arts and isn't very difficult to learn with the right felting supplies.
