A witch's ladder is made from knotted hair, hemp, wool or cotton & feathers or other charms. The number of knots and nature of charms varies with the intended effect or spell. They can also be used to "bind the thirteen moons of the year," purportedly to allow the witch to better work weather & nature magic & to open the doorway to the Faery realm. Many keep a personal ladder where the knots or beads are used to keep track of repetition in a spell or prayer, like Rosary beads.
I incorporated branches into my son's first room. It was jungle room, and I put stuffed exotic (fake) birds on the branches, and hanging monkeys. I also painted a jungle theme on his little furniture that my father-in-law built, and I painted a blue sky with clouds on the ceiling... Wish I would have taken photos back then!
