She first exhibited in 1927, at the Redfern Gallery, and an early woodcut shown at the 1927 SWE exhibition received significant praise in The Times. Such was the originality of her printmaking that she exerted an influence over Ravilious’ own wood engravings. She was also commissioned by the BBC in 1928 to illustrate Granville Bantock’s The Pilgrim’s Progress, and made whimsical but exacting observational pictures that were popular with children and exhibited by the Society for Education in Art.
While recovering from emergency mastectomy surgery in 1942 she wrote her autobiography, Long Live Great Bardfield & Love to You All (published posthumously in 2012). After Ravilious’ death that same year, Garwood remained in Essex until her remarriage in 1946. She was again diagnosed with cancer in 1948 and died in 1951. In 1952, a memorial exhibition was held at the Towner Gallery in Eastbourne.
