A few more clarifications please...I have the 3 Killings in the North which is at my front door.
My house is a bi-level where basically the front door is neither on the top floor nor on the bottom floor but in between. From the front door we can either take stairs to go up or stairs to go down from our landing.
Usually I have to put my cures on each floor, but since this one is right at the front door, if I have them right at my door is that enough?

I am also confused as to where they should be facing.
I thought that they should be facing our backs when we enter our home. We do not spend any time on the landing expect when entering, exiting and going up and down the stairs.
I have one of the left side of my left door and one of the right side of my right door. (I have 2 doors next to each other but mainly use the right one.)
The North is behind me when I enter my front door.
Do I have them placed correctly or should they be facing me when I enter the home?
I could place them on the left side of the stairs going down near the left wall of the entrance, and one of the right side of the steps going up, next to the right wall of the entrance.
Shawn's previous response explained that they should face the degree of the 3 killing, I wasn't sure what he meant.
Also, we do not always use the front door but use the garage as entrance since it is actually also a good direction for us. Not sure if that matters to decide what they should be facing.

Many thanks!
