OK...I have a boundary question.
Are we counting corners relative to being on OUR property, or from a standpoint of the back neighbor having a corner where we don't happen to have one? It so happens that the crook of the L is a corner for THEIR property, but that, from the view standing in our front yard, we have a fence that's flush with the front of the apt bldg, meaning that there isn't a corner for OUR property. I'm thinking it's relative to the lines we view on our property, and we're demarcating from that standpoint, so I didn't sneak onto their property to put a stake in that area, behind the fence, on what would be their back corner.
Otherwise, that was some Mission: Impossible business, putting those things in. Whew! I'm in a college town, right near the downtown area, and those kids would. NOT. GO. HOME. It was a Saturday night, and they were just popping up and hanging out everywhere! LOL!
There was menstrual blood mixed in the urine; I hope that's okay. I also "woke" the stakes up with some incense smoke before heading out. Used the silver dimes, but I have no graveyard dirt (my family is incredibly far away, so that was out of the question). When I was done, my apt was fair humming with energy; it felt crazy different. Could be the magic...could be the fatigue from it being 3 AM.

Hope it works.
Thank you, St. Expedite, for giving me the tools necessary to solve my problem completely and thoroughly. Blessings!
