1. See a Pattern
Bold printed wallpaper is back in a big way. Get in on the trend with peel-and-stick versions, like Hygge & West’s Nana Tiles in Pink ($58 for two 24-by-32-inch tiles).
2. Bright Idea
Swap a generic overhead light for a fixture that really shines, like this Light Society Sputnik 18-Light Chandelier. Score this model or similar (with bulbs!) on Amazon for under $100, and install a dimmer switch for instant dinner party vibes.
3. DIY Detail
Using stock trim, a nail gun, caulk, and paint, you can add wainscoting (and charm) on the cheap. Use a Web tutorial (like this one from DIY Network) and tailor the steps to your room’s specs.
4. Plant Something
Science shows that looking at greenery can improve your mood, so find a potted plant that thrives indoors, slip it into a decorative basket, and smile!
5. The Haute Seat
Bored with a plain-Jane table? Dress it up with new seating. This leggy model, the Alchemy Eagle Brown Dining Chair from Article ($299 each), mixes low-key leather upholstery with a glam golden frame. If funds are tight, buy a pair of statement chairs (Article has tons of colors and styles) and four or six less spendy options.
