saumattu

Saumattu is a Finnish adjective meaning “stitched” or “seamed.” It is used to describe textiles, garments, and other materials that have been joined by sewing along one or more seams. The form is derived from the noun saumaa or sauma, meaning “seam,” with the derivational suffix -ttu, so saumattu literally denotes something that has seams. The opposite form, saumaton, means seamless or without sewn seams.

In practical use, saumattu indicates that a product is finished with stitching rather than by bonding or other non-sewn methods. Saumattu garments typically display visible seams and standard sewing finishes such as straight stitches or overlock/serging, and may also refer to the general construction of the item as sewn rather than fused. The term is common in Finnish textile, fashion, and home sewing discourse as a straightforward way to distinguish sewn construction from other assembly methods.

In labeling and product descriptions, saumattu is often used as a descriptive attribute, with additional details about seam type, finish, or fabric provided as needed. Related terms include sauma (seam), saumaton (seamless), and ompelu (sewing).
