"Walls of Kindness" are popping up in cities across Iran for people to leave clothing for the poor or homeless.
The first wall sprung up in the north-eastern city of Mashhad, according to the BBC, where hooks were placed on a wall with the sign "If you don't need it, leave it. If you need it, take it."
The man behind the project, who wishes to remain anonymous, told local newspaper Hamshahri he's happy the idea has taken off: "I've told [people] to bring clothes in small quantities so that those who come here know that clothes are always available."
According to Radio Free Europe, Walls of Kindness have since sprung up in the cities of Sirjan and Shiraz.
With winter temperatures plummeting and a stagnant economy, the need for clothing donations is high. According to the Guardian, there are at least 15,000 people homeless in Iran's capital Tehran alone.
"We need to do it ourselves," this Instagram user wrote. "Life is too short. Be kind as much as you can."
