It is done.

I finished my ritual in record time. And, I did it right under my parents' noses. It's for their own good anyway. This is basically how the ritual went:

I cast the circle, as I normally do, including summoning the elementals. I then charged nine black plastic beads. I chose black because I find it is significantly connected to protection, and they are plastic so that they will not rot away. I charged the beads, which are on a loop of black yarn, in sets of two. In each set, there is a bead that pulls elemental forces from the Earth, and a bead that is a receptacle for Fey energy. I have made a promise with the Fey that as long as they willingly tend the shield, I will leave them offerings as often as I can. The last bead I charged as a focus for all good energy. I then charged them by the elements: Earth and Water in the tea that I had with me, Air from the incense that I blended for the occasion, and Fire from the flame of the candle. I passed them through the smoke and flame until the tea had dried. I then charged a sweet almond cookie as a preliminary gift to the Fey and a sign of good faith. I then closed the circle as I usually do and cleaned up my space.

The shield that I intend to set up is going to have four arching pillars, one in each Quarter, supported by a central column that is located right outside the front door of the house. The central column is the center point of the whirling spiral of energy contained within the shield. It will draw positive energy into the house, while repelling negative energy so that it may be grounded by the outer perimeter. The shield itself is semi-permeable. All negative energy is grounded or repelled, and all positive energy is allowed to pass through. The shield does not affect and is not affected by physical objects or creatures. If all goes according to my plan, the area contained within the shield will be an area of light and happiness, a place where my family can rest and be protected when they let their guards down.
