A seam finish is useful to neaten the seam’s raw edges and to prevent the fabric from raveling. It also makes the seam look neat and clean. A good seam finish not only adds longevity to a garment, but also it gives a professional touch to the sewn garment. When choosing a seam finish, the following factors should be considered:
Equipment at hand
The type and weight of the fabric
How much the fabric ravels
Whether the garment will be lined
The laundering the garment will be subjected to
The amount of wear and tear a garment will receive
A well-constructed seam finish should:
Be neat and smooth in appearance, without added bulk.
Protect the area and prevent the edge from raveling, stretching, rolling, or curling.
Not be visible from the right side of the garment.
