I've come a long way since then and I apologize for the pictures in advance. I've gotten a new phone recently, so the pictures should be a bit better, but the lighting in the area is still horrible. This area of the house gets no direct sunlight and only gets a wish of sunshine during the day.
Since all the walls are prepped, the first order of business was to find a pick out my cabinet for the corner. This definitely took 2 people: one to hold it up, one to screw it into the stud. This also prompted to me to purchase a stud finder. I'm usually very adept at finding studs in the wall, but this closet seems to defy all logic.
