FilzFelt carries German-milled 100% Wool Design Felt in over ninety colors and four thicknesses. Wool felt is one of the oldest man-made textiles and to produce felt, raw wool undergoes a wet felting process, which involves matting, condensing and pressing the fibers. Design Felt is high quality, eco-friendly (wool content!), comes in highly saturated colors, and is perfect for demanding design applications.
