The Swiss weaver Marianne Straub came to work with her and to learn more about hand loom weaving; Mairet taught Straub about hand dyeing and spinning as well. Straub introduced a variety of double cloth weaves and developed a friendship with Mairet. Mairet learnt in turn from Straub and this underwrote her belief that hand loom weaving could be used by industry. Straub and Mairet went on three European holidays during the mid 1930s. Straub frequently returned to Mairet and "Gospels". A surviving journal written by Mairet from a European journey with her husband in 1927 illustrates how her observations were dominated not by whom she met but what they were wearing.
