Natural Canvas – 18 Oz – #8 Duck | The Legendary Heavyweight Workhorse
When your project demands real, old-school toughness, built-to-last canvas, this is it: our 18 oz #8 cotton duck – the heavyweight champion of the numbered-duck family. Woven with true double-fill plied-yarn construction, it is dramatically stronger, denser, and more abrasion-resistant than single-fill fabrics, yet still sews beautifully on a walking-foot or industrial machine.
The tight weave and raw, undyed/unbleached finish give it that authentic warm ivory color and rugged texture that instantly screams “heirloom quality”. At a solid 18 ounces per square yard, this is the exact canvas trusted for decades for the toughest jobs on the planet.
