| Hem Options for Made-To-Order Tarps | |
 | Flat Hem: This is the standard hem that comes with this product. It consists of double-folded edges with grommets installed at either 2' (standard) or 1' intervals. The hem is then chain-stitched on either side. |
 | Grommets with Patches: Similarly to the Flat Hem, this hem is double folded with grommets installed every 2 feet. Unlike that option, though, this hem also includes patches of reinforced fabric underneath each grommet to provide extra strength. |
 | D-Rings with Reinforced Patches: Ideal for securing large loads, this configuration uses webbing and steel-plated zinc D-rings plus four-layer patches every 2'. The 1-1/8-inch D-rings accommodate standard webbing and handle heavier weights. Made in America, they remain reliable in harsh conditions. |
 | Rope In Hem: Spread load along the entire edge of the tarp, dramatically reducing the risk of tearing from tension. This is the option you want if your canvas tarp is going to be relied upon for the most demanding of jobs and conditions. |

Built to Breathe — Water Rolls Off, Moisture Escapes
Condensation Control: Airflow lets trapped humidity escape, cutting down on mildew that can form under fully airtight covers.
Moisture Balance: While the wax treatment sheds rain, the canvas still allows covered items to dry, helping protect cargo like lumber, produce, or machinery from rust or rot.
Temperature Moderation: A breathable cover reduces heat buildup, keeping stored items or covered work areas closer to ambient temperature.
Canvas Tarps in our 1974 Catalog
Humphrys began in 1874 sewing heavy cotton canvas covers for Conestoga wagons. These covers were tough then, and our tarps are even tougher now. Each tarp starts with premium 12 oz. cotton duck that is then given a 6 oz. wax treatment for lasting water resistance. The reliable construction that served 19th‑century wagon drivers still defines every cotton canvas tarp we make today.
Check out this advertisement we ran back in the early 70s —it’s a reminder that quality never goes out of style.
American History in Every Stitch
For 150 years, we have turned heavy cotton duck into covers built to work. Every tarp is still wax‑treated, cut, sewn, grommeted, and packed by hand in Indiana. From truck beds to farm loads, you get a U.S.‑made canvas that is ready for the long haul.
