Woollen Felt Sheet

Pressed wool felt is made via an intricate process often referred to as "wet processing". Fibers are worked together by pressure, moisture, and vibration, then carded and cross-lapped to make multiple layers of material. The ultimate thickness and density of the material determines the amount of layers that are then steamed, wetted, pressed and hardened.
The majority of fiber used in pressed felt is wool. Wool fibers have small barbs on them, which aids in the natural locking or felting process.
