Demkutė cared about the memory of old wooden architecture, and so she walked around Žemaitija region drawing authentic wooden churches.
Demkutė continued the graphic art traditions of Lithuanian folklore, using its dynamic ornaments in her carving, and contrasting colours in her illustrations to strengthen emotions as well as make it all more vibrant. Her prints were typically monochromatic.
As a child, Demkutė wanted to be a nun, however her plans were disrupted by World War II and the occupation of Lithuania. Later, she took her vows in secret. 1946-1951 saw her studying graphic art at the State Institute of Applied and Decorative Arts in Kaunas. She illustrated many books that were important for Lithuania’s culture over her career, both for grown ups and kids – books by Šatrijos Ragana, Juozas Tumas-Vaižgantas, Justinas Marcinkevičius, Antanas Vienuolis, and other prominent authors.
