Seat work and industrial occupations; a practical course for primary grades
A teachers' manual of seat work and paper folding for primary grades, written by Mary Louise Gilman and Elizabeth Baille Williams and published by Macmillan in New York in 1905. The line diagrams show flat paper shapes and the folded results — tents, houses, boxes — in plain outline with occasional hatching, useful as simple geometric net patterns and construction schematics.
