3mm Wool Design Felt
About
Our 3mm Wool Design Felt is available for product, furniture, fashion, and vertical surface applications. The possibilities are limitless! 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 a high quality natural material, comes in highly saturated colors, and is perfect for demanding design applications. Please visit filzfelt.com/about for more information on the manufacturing process and unique characteristics of 100% Wool Design Felt.

Variation Wool felt is a natural material and color variation and inclusions of natural fiber on the surface are evidence of the 100% natural origin of the material. Product color is only indicative, as it is not possible to assure consistency of color in a natural Product due to the natural color of raw wool and absorption of dyes. Color matching cannot be guaranteed on shipments and variation will be more pronounced beyond the normal commercial range.
