发明名称 Template for ruling index cards
摘要 The template for ruling index cards is a guide for marking a number of parallel lines on an unruled writing surface, such as a 3''x5'' index card. The template has a number of parallel slits spaced at predesignated distances from each other. Preferably, a template with horizontal slits is used in combination with a template having vertical slits to form a grid with horizontal and vertical rules for blocking letters, i.e., for creating blocks, which ensure uniform size and spacing of letters drawn on the index card. The template may be used to form a grid on a marking substrate, which is used as a guide for marking sweepstakes entries on the substrate. A transparency may be laid over the substrate, and cutouts formed corresponding to the entries to form a template for sweepstakes entries from the transparency.
