POD Niche Radar — Hugo Spritz Club, Beginner Tennis, Fibermaxxing, August 27, 2026

Week of August 21–27, 2026

This week's three picks sit inside one current: people are searching how to leave the screen and do something with their hands. Google's July 28 "touch grass" deep-dive and the June 23 Summergeist report both point the same way — beginner sports, homemade cocktails, fiber-heavy kitchen habits — and Redbubble supply on those long-tails is still thin enough to ship into.

Data note: Google Trends Explore/API remain rate-limited (HTTP 429). Demand % come from official Google Search posts (Summergeist, June 23, 2026; "Touch grass," July 28, 2026) and Google's Threads — not a live Explore export. Etsy is bot-blocked this run; supply is Redbubble primary (Aug 27, 2026). Missing Etsy counts are unverified, not zero. Printful catalog 404 — base costs from stable knowledge (tee ~$7–9, mug ~$4–6, poster ~$5–8, sticker ~$1–2).
