Grace Denny was one of the founding members of the Seattle Weavers' Guild. Miss Denny came to Seattle in 1914 to teach Home Economics at the University of Washington. (She was not related to the Denny family associated with the founding of Seattle). While at the University she was recruited by one of the major department stores in Seattle, The Bon Marche, to write some definitions about textiles and fibers so the store's buyers would know some thing about their textiles. This ultimately became the book known as Fabrics which was first published in 1923 and is now in its eighth edition.

At the April, 1937 meeting it was proposed that Mary Atwater's Recipe Book be purchased but the membership did not want to spend money from the Treasury at that time. By September of the same year, the idea of a library gained support. The Seattle Weavers' Guild Library now holds nearly two thousand items and is cataloged through Library Thing. Members can check out items when the library is open during meetings.
