#8 Cotton Duck Canvas Fabric – Natural 84" Wide | Heavyweight 18oz Duck Cloth
Our #8 cotton duck canvas fabric in Natural – 84" 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, upholstery, theatrical, and outdoor applications where maximum 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 oversized 84-inch width makes it especially valuable for large floor cloths, oversized wall coverings, wide upholstery panels, stage backdrops, industrial covers, large artist canvas projects, acoustic panels, and heavy-duty fabrication applications.
The Natural color showcases the authentic raw beauty of cotton canvas with warm organic tones and subtle cotton flecking from the unbleached fibers. Because the fabric is left undyed and unbleached, it remains one of the best choices for custom dyeing, painting, waxing, printing, scenic art, 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 projects requiring rugged structure, reduced seams, and long-term wear resistance.
The extra-wide 84" construction is especially popular with floor cloth artists, scenic designers, upholstery shops, theatrical production companies, industrial manufacturers, outdoor gear makers, and large-format sewing operations that require wide coverage and 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.
