When sourcing 100% linen, the price is primarily driven by fabric weight (GSM), yarn count (e.g., 14s, 17s, 21s), and finishing processes. Higher yarn counts result in finer, more expensive fabrics suitable for high-end apparel, while lower counts are used for heavy-duty upholstery. You must verify the density and tensile strength to ensure durability. Always request a fabric swatch or 'hand-feel' sample before bulk purchasing, as the tactile quality significantly impacts the market value of the finished garment or home textile.
