When would you typically use bias tape in sewing?

Bias tape is specifically designed for use on curves and edges that are not straight, making it ideal for binding the edges of fabric pieces or creating finished seams where the fabric may curve or round. This is due to the unique properties of bias tape, which is cut on the bias of the fabric. The bias allows the tape to stretch slightly, conforming to the shape of the fabric it is applied to without puckering or distorting it, which is essential when working with curved areas.

Using bias tape effectively can enhance the look of a garment or project by providing a clean, professional finish. It can also prevent fraying at edges and add a decorative element if a contrasting color or patterned bias tape is chosen. This versatility is why bias tape is predominantly associated with binding edges or creating finishes on areas of fabric that have curves rather than straight edges, which are typically handled with different techniques or materials.
