The creator of the present volume is probably Vera Margaret Hetherington, born in Brockenhurst, Upton Park, Forest Gate, London in 1892, but baptized in Staffordshire. If, as seems likely, Hetherington attended St. Mary's Hall in her late teens, she would have made the volume circa 1910.
In A.T. Vanderbilt's What to do with our girls, or, Employments for women (London: Houlston & Sons, 1884) St. Mary's Hall is described as "A College for Training Teachers upon Scriptural, Evangelical, and Protestant Principles ... Accommodation for 60 Students ... The marks obtained by students at the last examination were considerably above the average in almost all the subjects ... No difficulty in placing them [graduates of the College, in jobs]. All students in turn sweep their rooms, lay the tables, wash up cups and glasses. Those who cook in the practising kitchen clean all the utensils used; they also wash and get up some fine linen. Cookery: Two students in weekly rotation spend about four hours a day in the practising kitchen, where, under the direction of an experienced housekeeper, they bake bread and cook their own dinners."
St. Mary's Hall in Cheltenham was one of many Church of England Training Colleges for Mistresses, established to train women as teachers for church schools. Hetherington may have studied sewing as part of the set of skills all women were expected to know in late nineteenth-century Britain; or she may have been practicing her skills in order to be able to teach them to female pupils of her own in the future. The presence of a "practising kitchen" at the school seems to indicate that housekeeping and sewing skills were part of the students' own training, in addition to pedagogy. (The label pasted on the front of the book indicates that this was an official school book for the "Subject" of Needlework, rather than a book related to personal leisure sewing projects.)
