Do it! mix old and new
Display a collection of vintage finds, such as vases or teacups, on sleek modern shelving for a simple, gallery backdrop.
Lighting can work both ways – try adding contemporary polished metallics to a period room or a vintage-style chandelier to a more modern space.
For a genuinely eclectic finish, look for authentic second-hand furniture in charity shops, on ebay or at flea markets and vintage fairs.
