In 1885, two years after graduating from Cooper Union, Morse took a position at Tiffany and Company as a designer and painter of stained glass. Around this time, progressive American publishers began to commission artist-designers to design the covers of commercial books, rather than assigning the work to die-makers and engravers, as was customary. Morse grew interested in the emerging field of book-cover design while still at Tiffany’s. Perhaps in part due to her experience there, she developed an impressive ability to interpret nature motifs and historical ornament. On leaving Tiffany’s in 1889, Morse resumed her education at the Woman’s Art School while also working as an independent designer. She soon rose to the forefront of the first generation of artists to design commercially produced books.
