In her late twentieths, Butler made annual visits to the continent until the outbreak of war. She travelled to France, Belgium, Switzerland and Italy. In Paris, she studied drawing, figure drawing and fine art painting. While in Paris she became associated with the Newlyn school and went on to spend the summers of 1894 and 1895 in Newlyn in Cornwall. Newlyn at that time was the centre for a group of artists who were interested in plein-air subjects, many of whom had previously studied in France. She was attached to the Newlyn School, and Norman Garstin's studio in particular alongside contemporaries such as Walter Osborne and Sir John Lavery. Garstin like Osborne had been a pupil of the Antwerp master Charles Verlat. Butler established a friendship with Luke Fildes, Stanhope Forbes whom she met at Newlyn. The influence of the Limerick-born Garstin, and Forbes, and the contact with the Newlyn School informed Butler's development and remained an important influence on her work throughout her life.
