How Is Wool Turned into Felt?

The essential ingredient for feltmaking is, of course, wool. In addition to wool, the two key elements required for felting are water and soap.

Felt is created when animal fibers—in this case, wool fibers—become intertwined and tightly interlocked, forming a strong, durable material with excellent insulating properties. This process is achieved by working the wool fibers together using moisture, movement, and changes in pH.

In simple terms, the process begins by laying out thin layers of wool evenly, one beside another. The wool is then gently moistened with soapy water and lightly stroked. As the fibers begin to bind together, they are rubbed more firmly and evenly. Once the material has felted, it is rinsed, shaped, and left to dry. The result is felt—a solid, durable, and exceptionally strong material that is highly resistant to tearing.

Different types of felt require different grades of wool, depending on the intended use. Fine wool is ideal for clothing, hats, scarves, bags, and smaller accessories, while coarser wool is better suited for rugs, blankets, cushions, and other larger items.
