A seam is the line where two pieces of fabric or material are joined together, typically by sewing. It is an essential part of garment construction, as it helps create the shape and structure of clothing. Seams can vary in type, such as straight seams, zigzag seams, or flat-felled seams, each serving different purposes in terms of strength and appearance. In addition to clothing, seams are also found in other textiles, such as bedding and upholstery. Properly constructed seams ensure durability and can affect the overall look of the finished product. Seam allowances, the extra fabric beyond the seam line, are important for adjustments and finishing.
