Grommets are metal or rubber rings that make the edges of a hole in a piece of fabric or plastic stronger so that the hole does not tear with use. Tarps that are made to be tied down over whatever item they are protecting need grommets in their corners so that the twine or rope that is threaded through the holes does not cut into the sides of the holes or tear the hole out. Use grommets to guard against tearing the tie-down holes. Grommets are most easily set with grommet pliers, which function the same way for fabric or plastic tarps.

Mark the intended hole locations on the tarp with a pen if the holes are not already made.
Place the grommet pliers, which look much like a hole punch, over the mark for the intended hole. Place the bottom half the grommet, open side up, on the bottom holder surface of the pliers.
Place the top half of the grommet, open side down, centered over the hole mark. Carefully squeeze the pliers until the top holder surface of the pliers touches the top grommet half to make sure the pliers are centered over the two grommet halves.
Squeeze the pliers tightly and hold for two or three seconds as the top and bottom grommet halves are squeezed and pinched together, making a full grommet.
Remove the fabric from the center of the completed grommet, which is usually cut out during the process of pinching the two grommet halves together.
