Wow, Paul: that is very cool! Thank you for making this available.
I will note that when I set a custom text color (and a custom background image) and went to print the card, it showed up with the default text color in my print preview. This with Brave on Debian Linux.
I don't send enough QSL cards to be worth buying them in bulk. Using a tool like this to print them myself in black & white onto card stock is just right.
