#8 Cotton Duck Canvas Fabric – Natural 72" Wide | Heavyweight 18oz Duck Cloth
Our #8 cotton duck canvas fabric in Natural – 72" Wide is an ultra-heavyweight 18oz cotton duck cloth made from undyed, unbleached 100% cotton. This extra-wide heavyweight canvas is engineered for demanding industrial, artistic, utility, upholstery, and outdoor applications where wider seamless coverage is needed.
Built with a rugged plain weave double-filled construction, this heavyweight cotton duck delivers exceptional durability, structure, abrasion resistance, and long-term performance. The wider 72-inch width makes it especially valuable for large floor cloths, oversized tarps, wide upholstery panels, wall coverings, stage backdrops, industrial covers, artist canvas projects, and large-scale sewing applications.
The Natural color showcases the raw authentic beauty of cotton canvas with warm organic tones and subtle natural flecking from the unbleached cotton fibers. Because this fabric is left undyed and unbleached, it remains one of the best choices for custom dyeing, painting, screen printing, waxing, and specialty finishing applications.
Often referred to as chair duck or duffle bag canvas, #8 duck is one of the heaviest numbered cotton duck fabrics available. It offers substantially more body and durability than lighter duck fabrics, making it ideal for applications requiring rugged structure and minimal seam construction.
The extra-wide 72" construction is especially popular with floor cloth artists, upholstery shops, theatrical production companies, industrial fabricators, outdoor gear makers, historical reproductions, and large-format sewing manufacturers who want fewer seams and greater fabrication efficiency.
Need FR treatment? This fabric can be treated for fire retardancy (FR) upon request for qualifying industrial, commercial, theatrical, or specialty applications. Minimums and lead times may apply.
