Gardnerial Traditional witchcraft Part 1
It is most convenient to mark the circle with chalk, paint or otherwise, to show where it is; but marks on the carpet may be utilized. Furniture may be placed to indicate the bounds.
The only circle that matters is the one drawn before every ceremony with either a duly consecrated Magic Sword or an Athame. The circle is usually nine feet in diameter, unless made for some very special purpose. There are two outer circles, each six inches apart, so the third circle has a diameter of eleven feet.
 Having chosen a Pace proper, take the sickle or scimitar of Art or a Witch's Athame, if thou mayest obtain it, and stick it into the center, then take a cord, and `twere well to use the Cable Tow for this, and loop it over the Instrument, four and one half feet, and so trace out the circumference of the circle, which must be traced either with the Sword, or the knife with the black hilt, or it be of little avail, but ever leave open a door towards the North. Make in all 3 circles, one with in the other, and write names of power between these.
