A new tartan was designed by Doddie in collaboration with Berwickshire-based clothes firm ScotlandShop, in a bid to raise cash for his motor neurone disease research charity. The tartan features colours from the teams he played for: black and yellow of Melrose, blue and white of Scotland, and black of the former and white of the latter are also intended as a reference to his seven years with Newcastle Falcons.My Name's Doddie: The Autobiography was published on 25 October 2018 through Black & White Publishing.
On 31 October 2018, Weir appeared on BBC One's The One Show, where he stated that his charity had now raised over £1 million.
