Straight stitch

The stitch is worked by passing the needle in and out of the fabric at a regular distance.

[6] Running stitches are used in hand-sewing and tailoring to sew basic seams, hems and gathers; in hand patchwork to assemble pieces of light fabrics; and in quilting to hold the fabric layers and batting or wadding in place.

[8] Darning for decorative purposes, often referred to as Pattern darning, is an ancient technique in which parallel rows of straight stitches in varying lengths are arranged to form geometric patterns.

[9] Japanese Kogin embroidery is a pattern darning style from the island of Honshū, often worked in white cotton thread on rough, dark blue indigo-dyed linen.

[6] Running stitches are a component of many traditional embroidery styles, including kantha of India and Bangladesh, and Japanese sashiko quilting and other embroidery styles such as pattern darning and redwork.
