I did make my own "fonds de pages" for the vanilla covenant project.
As you may see if you look attentively at them, they are quite different from the original ones (Atlas Games' original ones I mean).
Do you need to use them in your own project?
You may freely download them here (and use them as you like) : http://david.berco.free.fr/storage/IMAGES_ArM5_Non_Official_Alternate.zip
How to proceed?
You'll have to use a desktop publishing software (or your simple word-processor).
I use them in Pages by Apple on Mac.
You may use them in LibreOffice (Write or Draw), Scribus or LyX which are free.
You may use them in Microsoft Word, Microsoft Publisher, Adobe InDesign, QuarkXPress or Affinity Publisher which need your money.
Put them in the rear plan (or background) of your document.
Pages named left shall go… to the left and pages names right…
Download the right fonts (listed in the rtf doc) and install them on your computer system.
Just download "A Vanilla Covenant" and get be inspired by its layout… (now it's no more a WIP…)
Do you really need more ?
