@mortaine Ooh, nice, I think I dowloaded (or bought?) the files for those as well quite some time ago, but never got to get them printed.
Mhh, you could just buy thin cardboard and use one of those manual braille punchboards to create the card.
I think I should have mine laying around and could TRY it, if getting it shipped wouldn't complicate it further...if I can find that thing.
Either way: Very nice idea from you!
