Warlock (It makes me chuckle when people think a Warlock means male witch. A witch is a witch regardless of gender. The word actually means Oathbreaker. Some jerk likely ratted out his coven during the burning times and the label given by the poor souls hunted down to him has been misconstrued to this day.)
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 wish people would stop acting like they know what they are really called just because they watch movies. I have news for you. The movies get almost everything about The Craft wrong. A Witch is a Witch (a keeper of the Earth) no matter what gender they are.
