A basic circle can also be a protective shield for yourself, an item, an object, or a space. See Part 2 for spells using this concept.
If it helps you, you can make a physical circle around your chosen space with a long cord or set a line of objects such as shells or rocks around you. Different people like different-sized circles; if you’re alone and not planning on moving around very much, a circle approximately 6 feet in diameter should be fine. Hold your arms out to the sides, fingers extended, to get a sense of how wide your basic circle can be. Plan to create your energy barrier slightly beyond your reach if it makes you more comfortable. If you’re going to be moving around the room, try casting the circle right to the walls.

Place each at the associated cardinal point
