koristus

Koristus is a Finnish noun meaning decoration or ornamentation. It denotes the act of decorating as well as the result—objects or arrangements added to enhance appearance, convey symbolism, or mark an occasion. The term is derived from the verb koristaa ("to decorate") with the nominalizing suffix -us.

Koristus appears across multiple domains including architecture, interior design, textiles, culinary presentation, horticulture and event planning. In buildings and furniture it may refer to carved or painted motifs, moldings and applied ornament; in textiles to embroidery, lace and printed patterns; in food to garnishes and plated accents; and in events to floral arrangements, lights and thematic props. Materials commonly used for koristus range from natural media such as wood, metal, glass and plant material to manufactured items like paper, fabric and plastics.

Techniques associated with koristus include carving, embossing, painting, appliqué, weaving, and lighting design. Choices about style and material often reflect cultural traditions, available resources, and the intended function—whether purely decorative, symbolic, or ceremonial. In Finnish contexts, koristus is prominent in seasonal and religious observances (for example joulukoriste, a Christmas decoration) and in traditional crafts where ornament carries historical or regional significance.

As a design concept, koristus intersects aesthetics, cultural practice and practical considerations such as durability and safety, and it continues to evolve with changes in technology and taste.
