Hi the template is really cool, love those examples ! :D
How do you open the .fig file ? With which software ?
Thanks for sharing !
With Figma!
Just drag the file in inside the software and you should be ready to go.
Here is the link for it: https://www.figma.com/
You can try to turn off all auto layout and resize everything by hand, after it just turn on auto layout.
But I don't recommend using small resolution because will make it not be very readable when printed. The size of the template should be something around 300dpi in the size of a standard card.
Also, another option is converting the image to SVG if possible.
