taittumia

Taittumia is a Finnish term used to describe folds or creases on a surface produced by folding. The singular form is taittuma and the plural is taittumia. The word derives from taittaa, meaning to fold, with the nominalizing suffix -ma.

In usage, taittumia appear in contexts such as origami instructions, bookbinding and printing, packaging design, textiles, and mapmaking. They denote the lines along which material has been folded or scored, affecting the final shape and handling properties. The term can refer to a single crease or multiple creases on a sheet. In English translations, taittuma is often rendered as crease or fold, and taittumia as creases or folds.

Understanding taittumia helps designers and craftspeople anticipate how a material will bend and lie when manipulated, aiding proper alignment, structural integrity, and aesthetics. In printed materials, scoring along taittumia facilitates accurate folding. In textiles, folds and pleats create taittumia that influence drape and texture.
