The hanging vines are chains wrapped with fake, green leaf vines. The chains make it sturdier to hang stuff from and can be found at hardware stores/Wal-Mart.
When my son was a baby, I decorated his nursery in a Jungle Safari Theme. The crib bedding & accessories are Nojo Jungle Babies.
I hung stuffed animal monkeys on the vines attached with a thin string. I also put vines on top of the hanging shelf around a few stuffed animals.
My favorite part of his room is the mural I painted on the wall.
