"Nuno" felt is produced by using a fine woven cloth to apply wool fibres upon. As the wool shrinks it takes the cloth with it, resulting in a crinkle effect. "Cobweb" felt is very thin and is made by pulling the fibres during the felting process so that holes or a web effect is formed. Many other techniques are used to produce a variety of weights, decorative finishes and uses. Application of heat, moisture and agitation are all that is needed and there are as many ways of making felt as there are felt makers - everyone has a different opinion about which way is "best"!
