Abstract
A tarpaulin composed of a sheet and edge reinforcing strips attached to the sheet along the edges thereof, only the strips being provided with perforations, at the intended locations of holding eyes, and the sheet being free of perforations so that the perforations in the strips present blind holes, whereby, for use, the sheet can be punched through only at the locations where holding eyes are required while the remaining edge portions of the sheet are left unperforated and thus unweakened.
