How to teach paper-folding and cutting: a practical manual-training aid
A teacher's manual for paper-folding and cutting, written by Norma MacLeod Litchfield and published by March Brothers of Lebanon, Ohio, in 1892 for use in manual-training and primary classrooms. The 82 line diagrams number each figure by hand and show polygons, inscribed circles, fold creases as dashed lines, and flattened cut-out patterns useful as geometric motifs, grids, or construction marks.
