There's unlikely to be anything more boring in your stationery drawer than the plain white envelope, which makes it the perfect blank canvas. This fundraiser for The National Brain Appeal returns in 2016 with a whole host of artists and contributors including Grayson Perry and Anthony Gormley who have created visual responses to the title 'A Letter in Mind' using the humble white envelope as their starting point. The results include paintings, collages, sculptures and sewn works. All of the creations will be sold anonymously for £85 each in aid of the charity.
