turnededge

Turnededge, often written with a hyphen, refers to a finishing technique in which the edge of a material is folded or turned to create a neat, protected border. The approach is valued for durability and a clean appearance and is used across various crafts and manufacturing processes, including textiles, leather, paper, and wood-based panels.

In bookbinding and case binding, turned-edge finishing involves turning the cover material over the edge of the boards and securing it to form a smooth, continuous surface. This can strengthen the binding and give a finished look to leather or cloth bindings, especially at the spine and corners.

In textiles and leatherworking, edges are commonly turned under and stitched or glued to prevent fraying and to produce a finished edge on garments, bags, belts, and other goods. Depending on the material and desired aesthetic, the turned edge may be done with or without an edging strip.

In packaging, display, and sign-making, turned-edge finishes can be applied to boards or panels where the outer layer is folded over the edge to conceal the core and enhance appearance. This is often seen in premium cartons, frames, and other high-end display substrates.

Terminology varies by industry; the term may be hyphenated as "turned-edge" or concatenated as "turnededge" in product names or brand contexts. The exact technique and naming convention depend on regional and sector-specific practices.
