When opening in GIMP you see a summary.

I have made a typical example MARCO POLO to show the principle of layers in GIMP.
There are two folder in the template:
beginners: I have merged several layer so that you can easily build a new card. The two examples are built only by copying layers from this folder. „beginner” doesn't mean, that you can build a card in ten minutes but it is simple enough to get a nice result.
The plaines are normed with (768x1146px). You can add a black edge to get an optimal export file (f.i. png) for a print.
If you want standard (696x1074px) for your home printer, you can load into every simple grafic program and cut 36px at every egde.
The other folder for experts shows the layers before merging, means you can change the color of the banner and text area etc. individually.
enjoy!
