Which finishing method helps prevent fabric from fraying at the seams?

Overlocking is a finishing method that effectively prevents fabric from fraying at the seams. This technique involves the use of an overlocker machine, which trims the edge of the fabric while simultaneously stitching it with a specially designed stitch. The overlocking stitch encases the raw edges of the fabric, securing them and preventing any threads from unraveling. This is particularly important for ensuring the durability and longevity of the garment, as fraying can lead to wear and tear over time.

In contrast, other methods such as notching, seaming, and felling serve different purposes. Notching is primarily used to reduce bulk in curved seams, and while it can help in easing curves, it does not provide protection against fraying. Seaming relates to the joining of two pieces of fabric and, although crucial in garment construction, does not specifically target fraying. Felling involves folding and stitching the fabric in a particular way to create flat seams, which also does not effectively prevent fraying like overlocking does.

Thus, overlocking stands out as the best method for preventing fraying at the seams, ensuring a clean and professional finish to the fabric edges.
