I am going to drywall my garage so it looks less crappy, bounces more light, and provide a nicer surface to hang poster/frames off.. Mostly re: the crappy look.

I've only ever done repairs and helped with mud, so I'm good there but never hanging a full room... No ceiling involved... Every "how-to" I see has you starting at the ceiling and working your way down... Any reason I cannot reverse that process ? I'm thinking if I'm by myself I can start on the bottom of the wall, once that sheet is screwed in, it can support the sheet above (resting on it) while I screw it in, which would make it easier as a one person job.

Am I missing a big trade secret no-no ? NOt going for superb inside the house finish here... Hiding pipes, and whatever hides between wood veneer...

Also, Bonus Q, one wall is already covered in old sheetrock (installed backwards! don't ask, no idea) which itself is covered by thin wood veneer (I told you my garage looked like crap). Is it acceptable to hang another layer of clean sheetrock over a layer of existing one, or not ? Thinking thinner drywall, 1/4 ? There's enough holes and gaps to see where the studs are but I'm guessing it might be too heavy even with longer screws and complicate the power sockets (now recessed)....
