Greetings @Amethyst! 
I can see you’ve already got some awesome advice here! Adding to what’s already been shared, I have a quick circle technique you might find useful. I usually use this one right before I go to bed when I’m in a new or unfamiliar place and crave just a little bit of extra protection. It can be done lying down, sitting, or standing. Your eyes can be open or closed when you draw the circle.
Quick Double-Layer Circle Protection
- Using the pointer finger of your dominant hand, draw a large circle in the air directly in front of you (or above you, if you are lying down)
- As you draw the circle, imagine it encasing the entire room- from wall to wall, enclosing the whole space.
- Take three deep breaths to set the circle in place.
- Next, use your pointer finger again to draw a smaller circle within the space that you drew the larger circle
- As you draw, imagine this smaller circle to encase just the space immediately around you- around your bed, chair, or the area where you are standing.
- Take three deep breaths to set the inner circle in place.
- Tell yourself you are safe and protected by the double layer of circle security
I hope you’re able to find some methods of circle drawing that work for you, Amethyst! Good luck and blessed be!
