Framing plays a significant role in the way a piece looks on a wall. Steer away from black frames, according to the Solomon Gallery. "Stick to neutrals, such as limed timber, gold leaf or white/cream-painted surrounds. Mounts should also be antique white or similar.

"Black frames and/or mounts have a tendency to overshadow surrounding artworks and are difficult to place in groups. With so many different woods already competing in a home, interiors customers are also opting for pictures that have non-wooden frames or no visible frames," says Works on Paper's David O'Donaghue.

Glaze paintings in kitchens and bathrooms, and protect valuable paintings with "Den Glass" (non-reflective).
