Available in different colours, materials, and thicknesses, knitting yarn decides the look and feel of a knitted garment. Natural options include cotton or wool or more luxurious materials like cashmere. Though the former are comfortable and soft, synthetic varieties are more durable.
Novelty varieties can create unique garments or crafts, and the thickness, or gauge, of the yarn should match a design's requirements. The correct knitting yarn for a project ensures the final product looks and feels excellent.
