Or,,,,, make a slip-knot and use a small stone,, put the rock behind the tarp and gather the material around it like a pocket, place the slip-knot around the stone and cinch it tight, now you can put a line anywhere you want and not damage the tarp! Also you can do like I did and raid the grandkidz marble collections and hi-jack the big ones,,,,,,,
