Selvages are the finished edges of a piece of fabric that prevent it from unraveling. They are created during the weaving process, where the weft threads are woven back and forth across the warp threads. The selvages are usually more tightly woven than the rest of the fabric to provide extra stability and strength.
Selvages can come in different forms, such as a simple folded edge, a raw edge, or a bound edge. Some fabrics have selvages with decorative elements like stripes, logos, or brand names, which can add a unique touch to the finished garment.
In sewing and quilting, selvages are often trimmed off before cutting the fabric into pieces for a project. However, some crafters like to keep the selvages intact and incorporate them into their designs for added texture and interest.
Overall, selvages play an important role in the production and use of fabric, providing structure, durability, and aesthetic appeal to a wide range of textiles.
