My family always has ropes up in our backyard. We string them up different ways and walk across them. Ours our sort of in the woods, so I did it for jungle week. You will need thin rope or strong string. I strung it from one tree to another, tying in the middle. Make sure to tie it really tight. You can add a top rope if you want. Now put a doll on and maybe a harness. I am using a string tied around Abby’s waist and a clip, more to keep her up then for her. Apparently Abby decided to go zip lining.
You can do this as many ways as you want. I just used the two strings so I did a tight rope, but we have done it more ways than I can count.
