Place a rock or other heavy object into a plastic bag, such as a grocery bag, and tie the bag closed.
Tie the bag to one end of the rope.
Gather both ends of the rope in your hands.
Stand back from the tree branch you would like to throw the rope over. Do not stand directly under the tree branch.
Throw the weighted end of the rope with an arched throw up toward the tree branch while holding the other end of the rope. Be careful to avoid the weight when the rope comes down over the branch so it does not hit you. You may need to attempt a few throws before your rope lands successfully over the tree branch. The weighted object will help direct the rope where you would like it to go.
