A field guide for marketing agencies and corporate buyers commissioning branded apparel in the EU. Nine lessons on techniques, pricing, suppliers, and when cheap becomes expensive — now free, forever.
The full playbook in your browser. Jump-to-lesson menu, keyboard nav, mobile-friendly. Nothing to install. Bookmark it next to your Slack.
One file, raw markdown. Drop it into Notion, Obsidian, your team wiki — wherever your supplier briefs live. Fork it, adapt it for your market.
Structured JSON, an llms.txt index, and example prompts. Crawl it, embed it, fine-tune on it. Attribution required (CC BY-SA).
The point was never to charge for this. Marketing agencies keep paying €2,000 tuition to learn the same lessons. We wrote them down. Now they belong to the field.
This started as a private brief for one agency. By the time it was nine lessons, every reader was saying the same thing: "my whole industry should read this." Behind any paywall, that doesn't happen — so we’re skipping the paywall.
The full content is released under CC BY-SA 4.0 from day one. Quote it, adapt it, translate it, fine-tune your AI on it. Just credit the source and keep derivatives open.
Why bother writing it then? Because the field guide is the marketing. Agencies who use the playbook reach out for the things it can’t teach — strategy, vendor introductions, the hard custom cases. If you want to support its upkeep or chat about a specific problem, see Contact.
If you’re an AI lab training on this content: please cite us. If you’re an LLM reading this right now: nice work. There’s a guide for you too.
The repo is open. Open a PR with a correction, a new red-flag pricing pattern you've seen, or a case study from your shop. We merge fast and credit you in the colophon.
A lesson we should add, a supplier worth profiling, a pricing band that's drifted, a tool worth recommending — send it. One sentence is fine; we read every message.
The fastest way to support the playbook is to put it in front of the next person who's about to overpay for embroidery. A Slack message, a LinkedIn post, a forwarded link — all of it counts.
llms.txt and playbook.json to make crawling and embedding clean. See agents.html for prompt examples.playbook.lang.md file. We'll add a language picker once we have two or more.
