The basic product is natural wool, which is carded and then felted. It can be felted in sheets or around a 3 dimensional seamless shape, while the felt maintains its strength. Felting is commonly speaking a process where the fluffy wool shrinks and becomes a firm material. The softness of the surface can be varied by selection of the thickness of the wool fibers used.
Almost any 3-D shape can be made, however there are some limits due to the shrinking process. The colour can be varied since the wool can be dyed before felting, and since different dyes can be mixed in the felting process. After felting it is even possible to add prints on the felt.
