This will be a long post. It's been a long project. I've got five days invested and have a couple more remaining. Also, I took a lot of photos.
I had some material left over from a previous drywall
DIY project (linked). I decided to tackle another project out in the shop using the remaining materials. I ended up using all the leftover stuff, and had to buy a great deal more material to complete this project, so that logic was a bit flawed...
