Calligraphy ruler

The perfect little tool to line greeting cards and envelopes. To use, line up against a ruler and use a mechanical pencil in the 'X' slots. Choose 3, 4, 5, 6, or 7mm x-heights. For the ascender/descender lines, the left column has slots with increments of 1:1 whereas the right column is 1.5:1 . Finish off by ruling the 55 degree slant and you're done!
