Custom Playmats

Hi gamers! So I recently got into the hobby of tabletop gaming, and it has become my favorite hobby, even over digital gaming. My biggest supporter is my girlfriend, who is always willing to play with me always allows me to share my interests with her. To show my appreciation I wanted to get her a custom playmat with our picture, and slots to place cards. I made a similar post to this on the everdell subreddit, because thats her favorite game. But now that i think about it, maybe it would be better to design a layout that can adapt to a lot different games? As our collection is still growing, I’m not too familiar on what the optimal layout would be for something like that. If you all could help me that would be amazing! :D
