For the technique of wet felting the wool or the wool fleece is placed on a surface, covered with hot soapy water and treated until the fibers start to stick together.
Then the workpiece is rolled with mechanical agitation or tumbled, a process which should be consistently carried out in all four directions.
During this procedure the surface of the workpiece will shrink considerably and at the same time the density of the entangled wool fibers will increase. As soon as the felted piece is ready it will not anymore change size and is washable up to 30 degrees Celsius.
