Harrods has launched a competition on Pinterest that will result in one consumer’s mood board forming the basis of its store window in celebration of the Queen’s Diamond Jubilee.

The London department store has posted its own inspiration page on the virtual scrapbooking site, formed around the idea of a street party for the occasion, and invited UK residents to do the same. All they have to do is then tweet their link to @HarrodsofLondon, along with the hashtag #HarrodsWindows.

Mark Briggs, image director at the retailer, will select three of the best mood boards to post on Facebook, from which fans will be able to vote for one to be transformed into a window by the store’s visual merchandising team next month.

The deadline for entries is April 19.
