Q: I recently relocated and took with me basically nothing. What's the best strategy to fill up an apartment? Should I buy everything at once? Or wait and build it out?
A: Even if you can afford to buy everything at once, it probably is not a great idea, because you risk ending up with a showroom look, which is never appealing. The goal is to be your authentic (and perhaps contradictory) self, not to buy into someone else's one-size-fits-all uniformity.
So aim for a home that looks like it was assembled over time. And the best way to achieve that — short of hiring people to scour online auctions, rural flea markets and vintage shops — is to take the time. Buy pieces you love and want to keep around. Enjoy the process of discovery. Find inspiration in your travels.
To create some coherence, before you start out, decide on an overall style and color scheme. Make mood boards from magazine clippings, visit blogs, comb through Instagram and home decor stores, antique markets and garage sales. Using these inspirations, lay a foundation of basic items like a sofa, coffee table, dressers and the largest table your kitchen will accommodate — it can function as dining area, workstation, extra counter space and family hub. The rest will follow.
Oh, and you'll need a mattress (perhaps I should have led with that?). It's expensive, but it has a major advantage: No one will see it, so it doesn't have to match anything that comes later.

Q: My pullout guest bed is in the middle of the living room (as they often are). I'm a renter and can't do anything structural, but I would like to make the area more private for guests.
A: Consider a folding screen. It can solve a multitude of problems, and add a dash of glamour to your home. While the screen can't replace an actual wall or door, it can be very effective at creating the illusion — or delusion — of separation.
Positioning a screen in front of a drafty window creates a cozy spot for an armchair (in French, folding screens are called "paravents," or "wind blockers"). Or you can use one to filter out an unattractive view without cutting off the light. A screen in a corner prevents the divan in front of it from "floating" in space. In a large room, a central screen allows you to delineate a small seating area (or space for a sleeping guest).
