Top Trending Print On Demand Niche Research T-Shirt Design Ideas #20 - Amazon Merch & Redbubble
About this video
Martinez demonstrates his niche research workflow in Merch Informer’s Movers and Shakers, looking for demand signals — especially when two designs in the same niche appear among the top sellers. Niches he pulls out include: reading (‘Just a girl who loves reading books,’ ‘Reading is my jam’); ‘favorite childhood memory’ sayings (e.g., ‘My favorite childhood memory is my back not hurting’); funny beer sayings, which he calls evergreen because they sell year-round as birthday gifts but get a boost around St. Patrick’s Day (March 17); baby gender reveal (‘Pink or blue, mommy loves you’); graduation 2023 — spotted partly by checking Instagram hashtags where graduation posts were minutes old — with graduation 2024 as the get-ahead follow-up; bonus dad (he uses ChatGPT to confirm a bonus dad is a man who helps parent another father’s child); forklift; sisterhood/funny-aunt sayings; birthday designs (e.g., sea-creature or llama birthday shirts with the child’s age); and leap year, to prepare ahead for the next one. He shows his spreadsheet system — sayings, niches, design layout and inspiration pictures shared with his team — and says he batches research into two or three days at the start of the month so he can aim for hundreds of designs a month. He also repeats trademark caution using Merch Informer’s Merch by Amazon trademark check, avoids IP like Star Wars without rights, and notes that putting one design on many products (hoodie, V-neck, tote, phone case, pop socket) lets Amazon cross-promote it.
Key takeaways
- Use Merch Informer Movers and Shakers and treat two sellers in the same niche on the front page as a demand signal
- Batch research into a spreadsheet (sayings, niche, layout, inspiration images) over 2-3 days at the start of the month
- Prefer evergreen sayings with seasonal boosts — funny beer designs sell all year and spike around St. Patrick’s Day on March 17
- Cross-check social media (Instagram hashtags) and tools like ChatGPT to spot and understand emerging niches such as graduation and bonus dad
- Check trademarks before designing and deploy each design across many product types so Amazon can cross-promote it
