It has been a long slog to finish the interior of my 26'x30' COVID garage since I decided to insulate and sheet rock myself.
But I think it came out pretty nice
Years ago we insulated and heated a warehouse at work and the contractor was delayed getting R-21 wall insulation delivered, so the impatient people at work bough (significantly more expensive) Owen's pink from HD, only to have the contractor deliver the day after HD order arrived. I inquired about what happened to all the extra material and found out it had been stuffed into a storage trailer and forgotten about. So I was able to purchase what I needed for ~1/3 the price.
wall insulation R-21

Bottom cords of the room-in-roof trusses are 2x8, but 8" kraft faced fiberglass batt wasn't in stock anywhere and was expensive to special order. So I doubled down on the deal from work and went R21 in the ceiling. (If I finish the attic room, I'll have a second layer of insulation above that, and I only intend to heat the garage when I'm working out there.... so called it good enough.

Strapped the ceiling using #3 1x Pine I had left over from my long ago pole barn build that I ripped down to size. I know a lot of folks don't strap, but I didn't want the 5/8 rock spanning 24" and didn't want but joints on the 2x bottom chords, so strapping it was.

Rented a lift to put the rock up on the ceiling. Day 1:

And day 2:

Walls went much faster...
