In tailoring, a floating canvas refers to a fabric panel sewn inside the front of a suit jacket or coat. The floating canvas adds structure to the front panel of a jacket, and ensures that the jacket drapes properly and maintains its shape over time. It is traditionally made from horsehair, woven together with wool, cotton, or synthetic fibers. The floating canvas is loosely handstitched in place between the outer jacket fabric and the inner lining.
A full canvas refers to a floating canvas that lies along the entire front of the jacket, from the shoulder seam and lapel to the bottom hem.
A half canvas refers to a floating canvas that reaches from the shoulder seam and lapel to halfway down the chest. A half canvas is often supplemented with fusible interfacing that provides structure to the remainder of the jacket front.
