What are four steps to treating raw fleece to become felt?

To treat raw fleece for felting, first, wash the fleece to remove dirt and grease, using warm water and a mild detergent. Next, card the fleece to separate and align the fibers, making them easier to felt. Then, lay out the carded fleece in layers, ensuring they overlap, and apply moisture and agitation to encourage felting. Finally, rinse and shape the felted material, allowing it to dry completely before use.
