Duck cloth

From Cornhole Wiki

Cotton duck (from Dutch doek,"linen canvas"), also simply duck, sometimes duck cloth or duck canvas, commonly called "canvas" outside of the textile industry, is a heavy, plain woven cotton fabric. There is also linen duck, which is less often used.

Duck is used in a wide range of applications, from sneakers to over tents to sandbags.

Duck fabric is woven with 2 yarns together in the warp and a single yarn in the weft.[citation needed]

Duck cloth is commonly used for the 6x6 inch corn filled bags for the tossing game Cornhole.
