The Medicine Shield makes a statement of our abilities and knowledge.
It is also a way of grounding the experiences we have undergone.
Your shield may represent your power animal, a special experience, a dream or an important journey.
Although traditionally a Shield is made from animal skin these days we use canvas on an embroidery loop.
A circle is the traditional shape.
You may draw on your Shield, stick things on it, hang beads, feathers, embroider it and hang it on the wall.
