One of Adelaide's teachers at this institute was es:José Fiter e Inglés, who awakened Ferré's interest in the history of needle lace.

[1] Ferré's pedagogic spirit, influenced by Serra i Pagès, is clearly evident in the research she carried out on any aspect related to textile activities considered feminine, especially everything that refers to lace.

Apart from the rigor and seriousness of her work, its relevance lies in the fact that, at the time she began to theorize about this art, the respective bibliography produced in Catalonia was very scarce.

Between the years 1931 and 1948, Ferré's main studies appeared in the Butlletí del Museu d'Art de Barcelona, an institution in which she collaborated by documenting its textile collection.

From Ferré's research, a large amount of data of great value and usefulness can be obtained when tracing a history of textile production both within and outside Catalonia.

The Marès Lace Museum hold two samples of bobbin lace designed by Ferré and made by ca:Clotilde Pascual i Fibla which were displayed in the 1918 exhibition in Barcelona at the Palau de les Belles Arts organized by the Fomento de las Artes y del Diseño.
