Take a thick piece of red wool, forming a square about 6 x 6 inches.(photo 1) With the felting needle, start punching along a line in the center of the square to mesh the fibers together. The felting begins. This punched area becomes flatter and hard. Fold the piece of wool in 2 and punch a line in the middle as described in the previous paragraph. (photo 2). Fold in two again ( photo 3). Next, work over the entire surface of the wool, punching a little bit everywhere to lightly mesh the fibers together.
