Last night I got the bulk of the dryall done and it feels great to see some progress. I installed 7 pieces, and have 4 more to go. To be honest, I am a drywall hack. I just hope the folks I hire to finish the seams and corners can work some of their magic.
The bay window area (to the left in the picture below) won't have the drywall installed until I get the windows and door in, since I will have to modify the widths and heights to make it more symmetrical.
