"Use and enjoy your antiques and unique finds, especially in a utilitarian room, like the bathroom." — Bunny Williams

"Straw, jute, rush—natural materials and neutral tones are always chic. They're the white T-shirt of interior design." — Meg Braff

Eye-catching tile can make a statement in the kitchen as well as in the bathroom. Cover as much of the wall as the budget allows, recommends designer Angie Hranowsky. Matthew Quinn agrees: "It feels more like a French bistro this way," he says of this blue-gray backdrop.

Neutral decor can be interesting if you include a variety of materials. "I used a range—from fine-gauge and open-weave linen, to raw silk and taffeta, to cotton velvet and distressed velvet," says California-based designer Ohara Davies-Gaetano. "Not only that, there's also the contrast of matte sheens that absorb the light, and lustrous sheens that reflect it."

For the perfect color family, mix one batch of paint 50% lighter than the base and another 150% darker. "That's a fail­safe method for striping a wall. It's also a very architectural way of using color." — Mary Douglas Drysdale

Mirrored panels like the ones lining this alcove can be elegant — but don't just slap them up, designer Jan Showers warns. Large sheets of mirror will look commercial, so try a sectioned pattern in the traditional French style instead.

"Put your money into a comfortable, well-made sofa that you'll have forever. You don't have to deny yourself that expensive designer fabric you love—just put it on something small, like a pillow." — Krista Ewart

"I'm really into saturated color with white to balance it out so it doesn’t feel overwhelming," — Joanna Gaines

"For classic side panels, you really have to go all the way to the floor. If you're looking at ready-made drapes, make sure that they touch the floor, even if you have to buy the next size up and have them hemmed." — Scot Meacham Wood

Glass shower doors add instant square footage. To complete the illusion, run the floor tiles straight into the stall. "It makes the room feel larger," says designer Alla Akimova. "If I had changed materials, it would have interrupted the space."
