staystitching

Staystitching is a row of machine stitches applied to a fabric edge to stabilize it and prevent distortion during handling and later sewing. It is typically done on the right side of the fabric, parallel to the edge, about 1/8 inch to 1/4 inch (3 to 6 mm) from the edge.

The technique helps when working with fabrics prone to stretching, especially on curved or bias-cut edges such as necklines, armholes, or edges that will be clipped and shaped. Staystitching is usually performed early in the construction process, either after cutting or before shaping and attaching pieces, to preserve grain, alignment, and accuracy in subsequent seams.

How to perform: place the fabric flat and use a straight stitch at a moderate length, typically around 2.0 to 3.0 mm (roughly 10–12 stitches per inch). Stitch along the edge, keeping the edge from being pulled or stretched as you sew. Backstitch at the ends to secure. The line is generally left in place and remains under the seam allowance or within the edge area, so it does not affect the garment’s final appearance. Staystitching may be removed later if it interferes with specific construction steps, but it is often left in place since it helps maintain fabric stability throughout assembly.
