Reunanauha

Reunanauha is a Finnish term describing a narrow strip used to finish the edge of a material. The concept applies in at least two domains: textiles and woodworking, where the edge treatment serves both protective and decorative purposes.

In textiles and garment making, reunanauha (edge binding) is used to finish raw fabric edges, prevent fraying, and give a neat, durable edge on garments, bedding, and crafts. It can be pre-made as bias tape cut on the bias or as a single- or double-fold binding that is sewn to the edge. Materials vary and commonly include cotton, polyester, nylon, or blends, with widths ranging from a few millimeters to a couple of centimeters. Application methods include machine sewing or hand sewing, and pressing is often used to achieve a smooth finish. The choice of binding depends on the fabric type, desired finish, and durability requirements.

In woodworking and furniture production, reunanauha refers to edge banding. This is a narrow strip applied to the exposed edge of boards such as plywood or particleboard to conceal the core material, improve appearance, and increase moisture and impact resistance. Edge banding is typically made from PVC or ABS plastic, but wood veneer is also used for a natural look. Many edge bands are pre-glued and activated by heat, while others are applied with adhesives or hot glue. Thickness and width vary by product and intended use, influencing the final appearance and durability of the finished edge.

The term reunanauha thus covers edge-finishing strips in both textiles and woodworking, with context determining the specific application.
