This Couple Invented a Genius Stamp System for DnD Maps and the Community Went Absolutely Feral

Every tabletop DM knows the struggle. You want to give your players an immersive dungeon crawling experience, but suddenly you are three hours deep into Photoshop, your printer is screaming in protest, and your dry erase marker has died a heroic but tragic death. Enter Jacob Harris and Karoline Moore, a Vancouver couple who accidentally solved this entire problem during what might be the most chaotic and adorable date night in crafting history.

It started with lino printing supplies. Karoline brought them home from a craft club, they carved little designs, stamped them into ink, and later that night Jacob floated off to sleep thinking about his next DnD session, because that is hoe all DMs fall asleep. In the fog between dreams and responsibilities, he had an idea that changed their lives. Get dungeons out quickly. So he nudged Karoline awake and pitched the idea of dungeon map stamps. She gave the universal partner response for late night ideas - "yeah, sure" and went back to sleep.

But the next morning, Jacob actually carved the first prototype. A simple weathered stone tile. And suddenly the impossible happened. He could build rooms faster by stamping them on scrap paper than any digital method. Fast forward to November, and their Kickstarter, Tabletop Stamps, shattered its 10k goal in 35 minutes(!) and blew past 250k within days. Why? Because this is brilliant. Analog. Fast. Accessible. Anyone can stamp a dungeon on an Amazon box while blasting fantasy music and ignoring email notifications.

The starter kit includes 25 stamps that cover everything. Floors, coffins, bridges, stairs, wells, textured tiles. You can stamp a 17 by 7 antechamber lined with coffins or a winding hallway that reveals itself as players move. It is modular map making but finally fun. And the approachability is part of the magic. Kids can use it. New DMs can use it. Veteran DMs drowning in prep can use it. The whole thing feels like taking creativity out of the computer and putting it back into your hands.

And of course, in classic 2025 fashion, this went viral because of TikTok. Jacob posted simple videos of maps forming second by second, and the internet said yes, absolutely, take my money. Now they are preparing manufacturing, talking retail, dreaming up new biomes, planning roller stamps that lay down walls in one swoop, and imagining entire city kits, swamp kits, sewer kits, trap packs, even Gloomhaven style hex tiles.

At the heart of it, though, it is just two creators who love tabletop gaming and accidentally made something that the entire community instantly understood. Something intuitive, joyful, and smart. As Karoline said, the DnD community is special, loving, supportive, and wildly creative.
