What is the purpose of stay stitching in sewing?

Stay stitching is a crucial technique in garment construction, primarily used to prevent the stretching of fabric layers, particularly along curved or bias edges. When fabric is cut, especially on the bias, it can easily distort or stretch during handling or sewing, which can lead to uneven seams and compromised fit. By using a stay stitch—a row of regular stitches sewn close to the edge of the fabric—seam allowances are stabilized, ensuring that the shape of the fabric is maintained throughout the sewing process. This stabilizing technique is particularly important for delicate or slippery fabrics that tend to stretch out of shape.

The other options do not directly relate to the primary function of stay stitching. Enhancing fabric color pertains to dyeing or printing techniques rather than structural stitching. Decorating the edges might involve techniques like hemming or embellishing, which are different from the functional purpose of stay stitching. Fixing lace onto fabric is a specific task that typically requires a different method of attachment, such as sewing or gluing, rather than the preventative measure that stay stitching provides.
