Sicksacksöm

Sicksacksöm is the Swedish term for the zigzag stitch, a common sewing stitch used to finish raw fabric edges and to join fabric pieces. On a sewing machine it is produced by setting the stitch pattern to zigzag; the stitch path alternates across the fabric edge, forming a zigzag line. The width and length are adjustable: a narrow zigzag hugs the edge for fray protection on delicate fabrics, while a wider zigzag can be decorative or better suited to stretchy materials.

Applications include finishing raw edges of woven fabrics to prevent fraying, neatening seam allowances, and providing decorative edging on hems or appliqués. It can also be used to join two edges with a flexible seam in lightweight or moderately stretchy fabrics.

Alternatives to sicksacksöm include overlock/serger stitches, pinking shears, or rolled hems, depending on fabric type and desired durability. The technique shares its name with the German Zickzackstich, and the Swedish term reflects this lineage, becoming common with the spread of household sewing machines in the 20th century.

Variations and considerations: some machines offer reinforced zigzag or overcast options to mimic a more durable edge finish. For very fine fabrics, test tension and stitch length to avoid perforation; for knits, use a stretch-friendly setting to preserve elasticity. Overall, sicksacksöm remains a versatile and widely used method for edge finishing in sewing.
