Spring winds here lean toward drama, which offers a challenge for any temporary roof repairs. I had a couple of garage sale tarps, the blue one frayed badly, the brown one a person could only see daylight through in a few places.
There was nothing obvious to do that would hold those tarps, nail-wise to keep them from ballooning in the wind. The sash weights, hopefully, will do the job.
The old water hose cows chewed through several years ago finally found a use, as well. Trotline cord threaded through pieces of it will hopefully keep the friction down enough to keep it from wearing through the tarps until materials for a better repair can be found.
