What is the purpose of the selvage edge on a roll of fabric?

The purpose of the selvage edge on a roll of fabric is indeed to prevent the fabric from unraveling. The selvage is the tightly woven border that runs along both edges of the fabric, which helps secure the threads together and prevents fraying. This feature is essential for maintaining the integrity of the fabric, especially when it is being handled, cut, or sewn. The selvage ensures that the edges remain neat and stable, which is particularly important in various textile applications, such as garment making and upholstery.

In contrast, enhancing color patterns, allowing easy cutting, or providing stretch capability are not functions of the selvage edge. Although the selvage might have patterns or colors that match the main fabric, its primary function is structural, ensuring that the fabric remains usable and manageable during the manufacturing process.
