Sashiko is a form of Japanese folk embroidery using a variation of running stitch to create a patterned background. The geometric patterns include straight or curved lines of stitching arranged in a repeating pattern. The Japanese word sashiko means little stabs and refers to the small stitches used in this form of needlework. Sashiko embroidery has been used in Japan for centuries, worked for both beauty and function. The designs in this style of embroidery can range from simple to complex, but they are all worked with a form of running stitch, known as, well, sashiko stitch!
