Crafty types, fashionistas and thrifty freecyclers are invited to join similarly minded people at a Late Studio at Somerset House tomorrow night (Wednesday 7 July). Titled White Elephant, as part of the Maison Martin Margiela exhibition, the idea is: buy a ticket, see the exhibition, bring with you any unwanted white objects for the white elephant stall, swap, customise, take apart and reassemble into something new with help from the 'expert transforming team' who will be there on the night. Be part of the photo shoot. Drink white wine. Listen to the white playlist. Tell us all about your white elephant efforts. Tickets are £15 or £10 concessions.
