I have made a simple QSL card which you can customise and print. I have made this using Libre Office on Ubuntu Linux. I have saved the file as docx also for those who are used to that format. I have used two fonts in this card, 'Arial' and 'Impact'. These fonts may not be natively available in all operating systems. For this reason, I have saved one version with embedded fonts option. That has increased the size of the file and you may download it if your system doesn't have these two fonts. You can download the files here as odt file, as docx file, as odt file with embedded font.
