seam means: The place at which two pieces of fabric join in sewing. The seam creates an invisible line in a garment’s surface. There are many types of seams. It all depends on how decorative the seam is, what kind of fabric is used and how stressed the seam is. Here are some of the most popular seam types. A plain seam can be made by joining the right sides and bottom of two pieces of garments. The seam will then be sewn on the fabric’s underside. The seam will appear on the inside when the pieces have been opened. To prevent seams from raveling, a seam finish might be required. A serger is a machine that makes plain seams. It uses a looping stitch, which covers the seam’s edges and prevents it from raveling. A flat felled seam, or a simulated one, is commonly used with sturdy blue jeans. It is a very strong seam with a double row stitching to hold it down. French seams can be used with delicate and sheer fabrics. They require many steps. First, a seam must be sewn to the right side. Then the right and left sides are joined and then another row is added that covers the seam. (in Fashion Dictionary)
