Maya didn't want to be the one to unravel the compromise. Yet the Book had become more than a repository; it was a battleground between craft and capital. To protect the Record, Rowan proposed a radical idea: surface the Book's provenance publicly in a controlled way. Not the designs themselves—never the patterns—but a narrative about PSG's history: the decisions that shaped its garments, the people behind seams, and the ethical lines they pledged not to cross. A living archive, curated but accessible, something to anchor identity if money tried to wash it away. psg design data book google drive
Today, if you search for the book on Drive, you’ll find a chaotic archive: OCR-scanned versions (searchable), photo-scanned versions (barely readable), a few watermarked official PDFs, and even an Excel supplement someone made for material properties. The links vanish and reappear with the seasons. | Feature Category | Specific Features / Data
