Elementary Brush-Work Studies (published in 1900), an educational book that teaches young children the technique of painting flowers and plants using her simple method. At the suggestion of Emery Walker, who worked with Morris on the Kelmscott Press, Yeats studied printing with the Women's Printing Society in London. In Dublin, she accepted the invitation to join Evelyn Gleeson to form the Dun Emer Guild along with Lily, who was an embroiderer. "The name Dun Emer (Fort of Emer) was named for the Lady Emer, wife of the hero Cúchulainn, renowned in Irish folklore for her beauty and artistic skills." Yeats managed the Dun Emer Press from 1902 with a printing press acquired from a provincial newspaper. The Press was located at Runnymede, the house of Evelyn Gleeson. (This house, located in Dundrum, was later renamed Dun Emer. It has since been demolished.) This was set up with the intention of training young women in bookbinding and printing as well as embroidery and weaving. In 1903 Yeats started printing and Dun Emer's first book was W. B. Yeats's In the seven woods (1903). Despite being a gifted printer, the costings exceeded the quality of work that Yeats produced with the result that the press (like the guild) was often at risk financially. Eleven books, decorated with pastels by George William Russell, appeared under the Dun Emer imprint produced from a first-floor room. Yeats had several disagreements with her brother William over his directions as literary editor. She also disliked Evelyn Gleeson. In October 1906 she travelled to New York to advertise her products but published Dun Emer's last book William's Discoveries (1907) in late November when she returned to Dublin. After many years of strained relations between the Yeats sisters and Evelyn Gleeson, their business relationship was finally ended. Subsequently, in 1908, Lolly and her brother William started the Cuala Press, publishing over 70 books including 48 by the poet. Yeats managed the press while her sister Lily controlled the embroidery section. Cuala continued to be a family strain. Their father, John Butler Yeats, had to castigate his son William for sending overtly critical letters to his sisters about the press. However, Cuala produced magnificent books: W. B. Yeats' The green helmet and other poems (1910) and a series of Broadsides (published 1908–15, with illustrations from Jack Yeats). Yeats was the first commercial printer in Ireland to work exclusively with hand
