The polymer £20 note is set for issue in 2020 and will follow the £5 polymer note, which was launched in 2016 and features poet Nan Shepherd, and the £10 polymer which was launched in 2017 and includes the portrait of scientist Mary Somerville.
Cranston is most famous for her series of tearooms across Glasgow, and her flagship venue is celebrated by designers due to the interior, which was designed by architect Charles Rennie Mackintosh.
The new £20 features illustrations of red squirrels on its reverse side as well as an image of the blaeberry fruit. It also includes extracts from 16th century Scottish poet Mark Alexander Boyd’s work, Cupid and Venus.
Although the notes will be issued in Scotland you should be able to use them across the rest of the UK.
