Deuchars attended Duncan of Jordanstone College of Art in 1983-1987 where she obtained a first class BA Honours in illustration printmaking.
In 1987 she was accepted to the Royal College of Art where she studied communication, art and design. In 1989 she received an MA with distinction.
Deuchars is most known for her distinct style of using hand lettering, which she first used in a D&AD annual report in 2002. To mark D&AD’s 40th birthday, the Annual Review was called “What’s the point”, which was art directed by Vince Frost and all 5496 words of the text was written in pencil by Deuchars.
Her distinguishable style has been used on stamps for the Royal Mail to commemorate the Royal Shakespeare Company’s 50th anniversary. Deuchars worked in collaboration with Hat Trick Designs to produce 6 stamps. Deuchars hand lettering also featured prominently for the British brand Cass Art, appearing in their shop front windows, as well as in Jamie Oliver cookbooks.
