Below is the inner page of an invitation I produced using
XeTeX. I repurposed a decorative border from
the frontispiece of Quadrans Astrolabicus, a 1534 book written by
Oronce Finé and printed in Paris by
Simon de Colines. The text is set in EB Garamond with occasional use of fancy ligatures and coloured initials. The whole invitation is printed on textured, A4-size card stock, folded in half to make A5 pages.
In case anyone would like to adapt the design for themselves, the complete and freely licensed source code is
available on GitHub.
