Pin-tucks are a flexible textile element that may be used to add texture to clothes in a variety of ways. They're made by folding the cloth in half and sewing the folded edge. When the fabric is opened flat, it leaves a slight ridge on the garment's surface.
It looks great on cloth and gives a simple garment a lot of variety and refinement. It gives a good appearance to use for kurtas, tops, dresses, skirts and more.
