What is the selvage on cloth or fabric?

The selvage or selvege is the edge that is created by the manufacturer during the creation of mechanically woven fabric. It will typically include information from the manufacturer such as design number or type of fabric. The selvage will also be a tighter weave than other parts of the material to prevent fraying or unraveling.

The selvage can also exist in the printing industry. It refers to the excess regions where the perforations are created.
