I've told you before that I'm not a fan of matchy matchy. But sometimes, repeating the same simple pieces in a room creates a luxurious effect that's muted, not headache-inducing. In this bedroom, the furniture and accessories sit in perfect symmetry, while the split headboard and sunny yellow pendant lights add a playful element that lightens the mirror-image mood.

Furniture: For the bed itself, you can go with a basic frame. As for the headboard, pick up a fabric with a palette matching your duvet, with a big graphic pattern such as these bursting chrysanthemums. Stretch the fabric over two tall canvas frames, a few inches less than half the width of the bed, and staple them to the frames. Pick up two matching nightstands in a medium wood with clean lines, such as the CB2 Acacia Nightstand ($149).

There's still lighting and accents to hear about, so read more.

Lighting: Bright yellow pendant lights, such as the Perch Walker Pendant Light ($190), hanging low over the nightstands will add a playful element and a boost of color.

Accents: Setting an array of small green glass vases and carafes by the bedside makes the nightstands mirror each other, but not to the extreme. Try the Pottery Barn Vintage Green Glass Jugs ($29-69).

Bedding: Start with crisp white sheets and pillowcases. Then, pick up a bedskirt and two throws with the same subtle, green/blue stripe. Next, find a duvet or matelassé with a big botanical pattern to set at the foot of the bed, and pick up textiles in a matching palette for the headboard. Two accents pillows with a graphic pattern in a coordinating color, like the Area Alma Pillowcases ($30 and up) will add an interesting visual element to the space.
