What is meant by "finished edge" in sewing?

A "finished edge" in sewing refers specifically to an edge that has been hemmed or serged to prevent fraying. This technique is essential because unprepared fabric edges can unravel over time, potentially impacting the durability and appearance of the garment or item being constructed. By finishing the edge through various methods—such as a hem, serging, or using a zigzag stitch—sewers ensure that the fabric remains intact and looks polished. This is particularly important in items that will experience frequent wear or washing.

The other options describe different states of fabric edges that do not meet this definition. For instance, an edge that is only pinned remains unprocessed and can fray, while a torn edge is intentionally left raw for a specific aesthetic but is not considered finished. Similarly, an uncut edge does not imply any treatment to prevent fraying, and thus cannot be classified as a finished edge.
