5 Easy Wins: Evergreen T-Shirt Niches You Can Upload Today (Low Comp)

About this video

RJ Martinez, who says he has done print on demand for over eight years, presents five evergreen t-shirt ideas he validated on Amazon using BSR charts (via Helium 10) and search-result counts, with AI prompts viewers can copy. The niches are: (1) a ‘just a lovely goose’ Valentine’s Day design — a cute goose holding chocolate hearts, flowers, or in a Cupid concept, with about one sale in the last 30 days almost three months before Valentine’s Day, which he takes as an early demand signal, and which he says can be remixed for St. Patrick’s Day or Thanksgiving; (2) a coquette bow grid in leopard/hearts style for Valentine’s, which he says also works for other holidays; (3) ‘just a girl who loves national parks’ in retro style, showing consistent BSR sales drops; (4) ‘please do not feed the wrestler — he’s cutting weight and may bite,’ a badge-style text design he calls evergreen all year; and (5) a ’time to sleep’ / official sleep shirt with a sleeping cat, close to 500K BSR with about four or five sales in the last 30 days. He generates concepts in Ideogram AI and Nano Banana (Gemini), notes AI output needs manual cleanup of misspellings and elements, and suggests editors such as Kittle, Canva, Photopea, Affinity Designer, or Photoshop. He also pitches his Top Research Design Vault at $10 a month for 20 niches weekly, saying it is approaching 1,700 researched niches.

Key takeaways

• Validate niches by BSR movement: isolated recent sales months before a holiday, or steady BSR drops, are treated as demand signals even at BSRs around 1 million.
• Remix one cute-animal concept (the goose) across Valentine’s Day, St. Patrick’s Day, Thanksgiving, and patriotic versions instead of designing each holiday from scratch.
• Use Ideogram AI and Nano Banana prompts for concepts, then manually fix misspellings, remove backgrounds, and recombine elements in an editor like Kittle or Canva.
• Make one-color text designs in both black and white versions so the same design works on light and dark shirts.
• Keep listing text readable on the mockup and target keywords for buyer intent on Merch by Amazon and Etsy.
