From the finest showrooms in Europe to the hidden gems of eBay, Los Angeles interior designer Kishani Perera relies on an array of resources to create beautiful spaces that have seemingly evolved over decades rather than months. This ability to blend the reclaimed with refined, the ordinary with ornamental, has attracted a loyal following of clients. A UCLA grad, Perera's love for design and all things vintage even inspired her to open a retail boutique, Rummage. And most recently, she published a book of her work, Vintage Remix (2012 Abrams), which features projects like a sprawling Hollywood Hills home to a New York City apartment. Learn her tricks of the trade, from deciding when to skimp or splurge to adding the finishing touches and unexpected elements of whimsy.
