Just been cleaning an old tarp. Its been over a vehicle, was growing moss and getting a bit slimy after rain,
Its a good old heavy canvas tarp, a throw-out from industry for being torn with many patches, some of which were spreading. I’d cut a bad section out of it and made it two smaller tarps. Its been very useful and I like it because its heavy and doesn’t flap around in the wind like flimsy plastic ones.
