The Running Stitch is an easy, basic embroidery stitch that creates line on the surface of fabric. Arrange lines of the Running Stitch to make patterns like that above or combine it with other stitches to make wonderful texture. (See examples below.)
To mark a line on cotton fabric for stitching, draw on fabric with the needle tip or your fingernail. To make a straight line, place a ruler on the fabric, run your fingernail next to the ruler, and stitch in the groove.
Combine the Running Stitch with other stitches like French Knots to make great textures like this.
