A large quantity of their work is held at Te Papa, in Wellington and the Auckland War Memorial Museum.
[1] After finishing school Josephine found employment at a photography studio in Auckland and Sybil trained as a nurse.
They spent a year touring around England, Ireland, France and Italy in a new Renault open tourer.
After graduating they purchased looms and other equipment required for starting a hand weaving studio and returned to New Zealand.
Through training these two women the sisters expertise that they had gained in England was passed on to further weaving in New Zealand that had yet to encounter their more proficient techniques.
Among their pupils was Florence Atkins who went on to begin the first weaving class in New Zealand at the Canterbury University College School of Art.
This move saw the studio name change to 'Taniko Loom-Craft Weavers' in order to distinguish the business from producers of machine knitting.
Florence Aitkins, used the teachings of the Mulvany sisters to form the weaving curriculum at the University of Canterbury and passed on that knowledge to hundreds of students.
