'That belgian flags guy'

About Vincent De Nil, founder of Flagmaker & Print

Vincent De Nil is a Belgian graphic designer, concept artist, and vexillology enthousiast working from Stockholm, Sweden and Raleigh, NC. He is the founder of Flagmaker & Print - the custom flag design and printing service trusted by worldbuilders, sports teams, community organisations, schools, and flag hobbyists across the United States and beyond.

Vincent's background is rooted in visual storytelling and historically inspired design. Long before Flagmaker & Print existed, Vincent was obsessively designing flags and propaganda posters for fictional nations: a discipline that demands the same deep understanding of colour theory, symbolism, and compositional balance that makes a real-world flag effective. That obsession turned into a profession, and eventually into a platform.

Since 2016, Vincent has been running an internationally operating e-commerce company from both sides of the Atlantic. His unique US and EU platform gives Flagmaker & Print a truly global character: European design sensibility, US market focus, and worldwide manufacturing and shipping capability.

Developing a flagmaker

In 2019, Vincent launched Kaiser Cat Cinema. This is a YouTube channel dedicated to alternate-history storytelling across four original fictional universes: WW2044, The Cold War, The Divided States, and American Kingdoms. The channel grew to over 130,000 subscribers by producing documentary-style videos, lore deep-dives, and original flag and propaganda-poster art for imagined nations and timelines.

Each Kaiser Cat Cinema video required designing flags from scratch (150+ designs as of 2025) applying real principles of good flag design to entirely invented polities. This practice is something the North American Vexillological Association (NAVA) actively promotes: understanding what makes a flag work in the real world by testing it in fictional ones..

The channel's webshop proved the demand. Viewers began ordering hundreds of flags and, crucially, they wanted to customise them.

Building Flagmaker & Print: The Tool Behind the Store

Flagmaker & Print launched in 2020, built during COVID lockdowns with a small team. The founding premise was deliberately simple: the easiest way to design and print your own flag online. That meant building the free built-in flag maker app directly into the store — not as an afterthought, but as the centrepiece of the entire product.

Today, the platform hosts over 14,000 custom flag SKUs covering everything from US state flags and historical flags to pride flags, fantasy and worldbuilding flags, and fully personalised custom designs. Every product in the catalog has been reviewed and tagged by Vincent personally, ensuring consistent quality standards across the entire range.

Flags are printed on high-quality polyester with vivid dye-sublimation printing, with header and grommet options for outdoor or indoor hanging. Full specification details — materials, size options, print method, care instructions — are covered in the Custom Flag Details & FAQ.

Vexillology Knowledge: The Wiki & The Vehement Vexillographer

Vincent writes under the pen name The Vehement Vexillographer: A nod to the passionate, opinionated tradition of flag criticism that runs through the vexillology community. His planned Flagmaker & Print Knowledge Center covers flag design principles, the history of national symbols, flag etiquette, and practical guides for designing flags for sports teams, organisations, and fictional worlds.

Future articles in the Knowledge Center will include:

The vexillology field is served by organisations including the North American Vexillological Association (NAVA) and the Fédération internationale des associations vexillologiques (FIAV). The study of flags encompasses design, symbolism, history, and protocol. Flagmaker & Print sits at the intersection of that tradition and the practical needs of designers, hobbyists, and worldbuilders who simply want to make something great.

Flags for Worldbuilders: The KCC Universe Projects

Much of Vincent's original flag design work lives in the Kaiser Cat Cinema universe projects. These are worth knowing about, because they demonstrate the depth of the creative practice behind the store:

  • WW2044 — A near-future Imperial German retrofuturist timeline. Flags, insignia, and propaganda posters for a world where the 20th century took a radically different path. This project represents Vincent's most fully realised visual identity work, combining Wilhelmine heraldic traditions with science-fiction aesthetics.
  • The Divided States — An alt-history comic series imagining a fractured United States, with regional flags and symbols for each breakaway polity.
  • American Kingdoms — A medieval re-imagining of American history as an Arthurian epic. Heraldic design meets founding mythology.
  • Kaiserreich — Documentary-style videos covering the famous Kaiserreich: Legacy of the Weltkrieg alt-history mod for Hearts of Iron, set in a world where Germany won the First World War. This is one of the longest-running and most beloved alt-history mods in the PC gaming community, with an active player base and an extensive community wiki.

Vincent's Kaiser Cat Cinema YouTube channel and its Patreon community represent years of consistent, original creative production — the kind of track record that builds genuine expertise, not just familiarity.
