Step 6: String it up!
Again, the photos make this simple to visualize.
Then, tie the ropes to a tree branch. Keep in mind that a higher tree branch will create a longer arch than a lower one. It lets the swing go farther with every push, which makes it more fun.
Tie one end of the rope to the tree, and then make sure the swing faces the direction you want it to. Set the swing at the HEIGHT you would like it to be at. Tie the other end of the rope to the tree branch. If you tie the two ends of the ropes rather wide apart from each other, it prevents the swing from twisting.
Make sure the swing is properly secured and tested before putting your tot in there.
