I am an amulet maker in training. Triangle shapes are often used and its a first for me. How reassuring to have a tangible object that promises protection. Often hung in doorways or on tree branches or beloved animals or baby cribs...an ancient and current practice. The shape, knots, tassels, beads, metals and assorted objects are part of the amulet makers work table. I'm planning on 4-5 in order to take on the beauty of this ancient form of prayer.
