How To Research Print On Demand Products That Actually Sell With Kittl

About this video

Martinez walks through his full research-to-design process, stressing that research comes before design and that the goal is proven demand. He starts free on Amazon Hot New Releases, scanning categories like 100 Days of School, and reads the Best Sellers Rank (BSR) chart: the lower the BSR drops, the higher the sales velocity — he points to one design down near 26K BSR and claims it is probably making over a hundred sales a day. Throughout he warns about copyright and trademarks, saying not to make designs for NFL teams like the Eagles without rights and noting he found ‘Gulf of America’ is trademarked. His second route is merchresearch.com: search US t-shirts, sort by newest arrivals, and look for new listings that already have a BSR, checking phrases with the Merch Informer trademark checker. He then screenshots a selling design (e.g. ‘All You Need Is Love and Data’), pastes it into ChatGPT and asks for ten related ideas, getting variants such as ‘All You Need Is Pizza and WiFi’, ‘All You Need Is Plants and Peace’ and ‘All You Need Is Books and Tea’, which ChatGPT also maps to target audiences; he does the same for a 100 Days of School friendship-bracelet concept. Finally he builds the chosen ‘pizza and WiFi’ design in Kittl: he picks the Merch by Amazon artboard template, uses Kittl AI’s design and image generators (mentioning DALL-E 3 and Flux 1.1 Pro options), replaces elements, removes backgrounds, and exports ready to upload. He says a 25% discount code for Kittl for new users is in the description, and advises designing about three months ahead of events.

Key takeaways

• Use Amazon Hot New Releases to spot trends early, and read the BSR chart: a falling/low BSR means sales velocity, which he treats as proof of demand.
• Use merchresearch.com sorted by newest arrivals to find freshly uploaded designs that already have a BSR — early demand before a niche saturates.
• Check every phrase for trademark/copyright risk (he uses Merch Informer’s trademark checker plus Google) and never use team or brand IP like the Eagles without rights.
• Screenshot a proven design into ChatGPT and ask for 10 related ideas — remix the concept (‘All You Need Is…’) for a different audience rather than copying the design.
• Build in Kittl on the Merch by Amazon template and export with background removed; he also advises designing roughly three months ahead of seasonal events like 100 Days of School.
