Some towels feature tread lines—raised patterns that reinforce the fabric to prevent fraying and preserve thickness over time. Many also use a dobby weave, which creates stable patterns that resist stretching and distortion,

helping the towel keep its form. Dobby borders, found on the edges, add strength and prevent unraveling, while also contributing to the towel’s aesthetic. Altogether, these lines turn a basic towel into a thoughtfully engineered textile designed for everyday performance.
