Polished off the sanding tonight (that's almost a pun, right?), filled in a couple nicks and called it a night.
You'll notice I skipped the inside side panels of the drawer.
I started them, as you can tell from the picture. I started them and quickly decided it wasn't worth it. They'll only be visible when the drawer is open, and oh my god all those corners! If I were to do it, it would take another 4 hours; I honestly do not have it in me.
I filled in a tiny hole on the top and a nick on the side using Elmer's Carpenter's Wood Filler. I didn't have a putty knife so I improvised with a plastic fork and my finger. It worked just as well and I'm no worse for wear. Let each spot dry 15 minutes, touched it up with some fine-grit sandpaper and considered throwing on a coat of primer.
I ultimately decided to save the primer for tomorrow. I had the time and the energy to throw on a coat of primer and close up shop for the night; however upon reading the directions, I realized I would need to leave the garage door open while it dries. Which is fine, just not at 10:00 PM. So, that's my plan for tomorrow. Layer of primer when I get home from work, pack for an hour, repeat. The directions say to use 2-3 coats,
