re: Those of you who work from home, what are some musts for your office?

Well, my real home office is the kitchen (side hustle is baking for farmer's market), but I doubt you're using 19 sheet pans in one day like I do. Most important equipment in that home office is three sinks. LOL.

Extra bedroom is non-kitchen office. I had it set up as a second guest room w/spare bed, but realized no one slept in the damn thing, so I removed the bed. Much more pleasant to be able to float the desk in the center of the room, where the natural light from the window is best. I added a rug and some art on the walls.

But the most important thing, to me, are noise-cancelling headphones. Even when no one is home, the annoying small noises of traffic, trash truck, AC, fridge compressor, etc can be magnified. In a busy office, it's easy to tune out background noise. In a quiet space, the little noises become huge. And if you're working while there is plenty of other (more fun sounding) activity going on in the house, they're necessary.
