Curvilinear is a style characterized by the use of curving lines (swirls, spirals, circles) to form abstract patterns. Curvilinear abstractions can be found in many cultures around the world and throughout history. The curvilinear style is often associated with more organic, natural forms, as opposed to the straight lines and geometric shapes of the linear style.

Curvilinear patterns are often used in decorative arts and design, as they can add a sense of movement and flow to a composition. They are also popular in tattoo designs, as the flowing lines can create a beautiful and intricate design.
