It is a fabric pattern with arches and tiny circles to express the image of dewdrop on the lawn grasses. This pattern is often combined with other motifs such as seasonal flowers. The pattern can be often seen on the costume of Noh or kimono.
Since the expression of dewdrops on the pattern creates the image of coolness, it is often used for a summer ceremonial kimono.
On the other hand, some of tsuyu-shiba patterns are depicted with autumnal plants such as Japanese silver grass and chrysanthemums, or snow scene, so this pattern is used in and out of season as the kimono fabric.
