Eight-plus years on production systems. At IBM Event Streams I work on Kafka Connect, schema registry migrations, and Kubernetes operators, and write about the failure modes that show up after deploy.

I wanted a bookmark I could print at home — not a craft project and not an account, just a PDF I could fold and stick in a book.

Foldmark does that in the browser. Pick a shape, type a line, pick a palette, download a PDF. The on-screen preview and the printed sheet share the same layout code, so what you see is what you fold.

Shapes
#

  • Accordion fold — the whole sheet, fan-folded thick. Numbered fold lines, no scissors.
  • Corner pocket — cut a square, fold twice, slide it over the page corner.

What else
#

Five palettes (including a dark Night press), cover motifs from the Foldmark logo set, patterns or your own image, A4 / Letter / A5 / Legal, color or black & white, and a shareable design link in the URL. PDF generation is all client-side with pdf-lib — nothing is uploaded.

Night press — dark paper, light ink, still the same print-and-fold flow.
