Kerrostusommel

Kerrostusommel, also known as couching, is a decorative embroidery technique. In this method, one or more threads are laid across the surface of the fabric and then secured in place by a second thread that stitches over them. The couching threads themselves do not pass through the fabric. Instead, they lie on top, creating a raised or textured effect. The securing stitches are typically small and evenly spaced, holding the couching threads taut and in the desired pattern.

Couching can be used to create a variety of visual effects, from outlining and filling areas to forming intricate designs. The threads used for couching can be the same or different from the securing threads, allowing for a wide range of color and texture combinations. This technique is versatile and can be applied to various fabrics, making it suitable for both fine needlework and heavier upholstery. Historically, kerrostusommel has been employed in many cultures for embellishing clothing, tapestries, and religious vestments, often using metallic threads to add richness and luxury. The appearance of the finished work can range from smooth and flat to highly dimensional, depending on the weight and number of couching threads used and the spacing of the securing stitches.
