I just wanted to share what the playmat looks like right now.
Edit: To answer questions I received, the blank character card was made with the GNU Image Manipulation Program (GIMP) 2.10. The original dimensions are 1000×700 but I place the card at 50% size, 500×350, so it will look good even zoomed in. If you would like to use them, here is an archive with .xcf, .psd, and .png format files. The fonts used are Alenia by shanayastudio and Spotnik demo by Alexatype.
I place copies of the blank card on the Map & Background layer on Roll20. The character info is filled on the Objects & Tokens layer in Contrail font.
