A seam is a line where two pieces of fabric are stitched together, forming the structure of a garment or textile item. Seams can vary in type, such as plain seams, French seams, or flat-felled seams, each serving different purposes in terms of strength and appearance. They are essential in clothing construction, ensuring that pieces fit together properly. In addition to clothing, seams are also found in other textiles, such as bedding and upholstery. The quality of a seam can affect the durability and overall look of the finished product. Proper seam techniques are crucial for both functionality and aesthetics in sewing projects.
