紗綾形 ・ さやがた ・ sayagata
A repeating geometric pattern consisting of connected left and right facing manji (swastikas). A manji is a traditional Buddhist symbol. The design is often angled and slightly skewed. Frequently used as a basic background weave in rinzu (satin damask) fabrics, but can also be used as a large all-over pattern or in combination with other designs. Both the line design and negative space between the lines are used as a design element. It is considered a lucky pattern.
The pattern is named after the fact that it was one of the patterns commonly woven in saya, a glossy silk fabric that was popular in the Momoyama and early Edo period in Japan.
