Wool comes from the fleece of sheep and is categorized into various types based on the breed and characteristics. The most common type is Merino wool, known for its softness and warmth. It is often used in high-quality clothing and outdoor gear. Another popular type is Shetland wool, which is coarser and more durable, making it ideal for traditional knitwear and blankets. In addition to sheep wool, there are other types like alpaca wool, which is softer and hypoallergenic, and cashmere, sourced from goats, prized for its luxurious feel. Each type of wool has unique properties, making it suitable for different uses in fashion and textiles.
