The Magick Circle

The magick circle is debatably the most important part of witchcraft. Without the magick circle then your magick is not as focused, the witch is not protected, and your success isn't as probable. Now, there are several ways to cast the magick circle ranging from a plain, simple circle to a complex multiple layered circle with sigils, invocations, and many other aspects. For a beginner it is common sense to start off with a simple circle as they should be starting with simple magick. If you have never cast a circle before or done any kind of spell, trying to do a more complicated spell or ritual is probably not going to work and could be dangerous.
The magick circle can be drawn with a piece of chalk, a string, traced in sand or dirt, or simply imagined(often though you might accidentally step outside the boundaries though). Another method that many experts use is drawing or painting the circle on a piece of wood, fabric, or paper of some kind. I myself just recently found out about this method and finished one myself yesterday. The thing with this is that it saves time from having to draw the circle itself and writing out all of the sigils and words that you may use when casting the circle. If you are going to do this then you will want to make it so that it isn't limited to only a few kinds of rituals, it should be more general so that you can use it in almost all of your rituals because they are large and take time, patience, and skill to make.
Here are some pictures oh some magick circles that might give you an idea. The first will be mine and the rest will be some more famous circles in history.
