Seams are the lines where two pieces of fabric are joined together in sewing. They are essential in creating garments, upholstery, and other textile products. Different types of seams, such as plain seams, French seams, and flat-felled seams, serve various purposes, including strength, durability, and aesthetics. In addition to clothing, seams are also found in other materials, like leather and canvas. Proper seam construction is crucial for the overall quality and longevity of the item. Seam allowances, the extra fabric beyond the seam line, are important for adjustments and finishing the edges to prevent fraying.
