Most consumer writing about textiles, food, and household goods is marketing. Some of it holds up under peer review. Much of it doesn’t. A surprising amount is flatly contradicted by the studies it cites.

Each project here covers the same things in the same order: history (told chronologically), studies and nuance, maintenance and use, cost, further reading, and sources. Every factual claim has a footnote. Where the evidence is contested, both sides are presented. Where popular wisdom is unsupported, it is named.
