I Tested Kittl’s 2026 Trend Report… These 3 Styles Print Money (Amazon Merch + Etsy)

About this video

Martinez tests what the transcript calls Kittl’s 2026 Trend Report (rendered as ‘KD’ in the captions) and builds three print-on-demand designs live for Amazon Merch and Etsy. The workflow for each trend is the same: download or screenshot the trend example, upload it to ChatGPT — he notes he has the paid version so he can upload images and dictate prompts — and have it generate design concepts with Prompt A, B and C plus who is buying it and why it sells, then generate and refine the art in Kittl’s AI backend, where his favorite model is Ideogram 3 (he also mentions Nano Banana performing well), before upscaling, removing the background and making the design big on the canvas for the Merch thumbnail. Trend one is signal graphics — loud, bold, readable — producing a ’90s nostalgia design, ‘Raised on cartoons and dialup,’ his favorite of that set. Trend two is blueprint designs — arrows and breakdown diagrams for passionate niches, foods and collectibles — producing coffee concepts including an espresso machine diagram and ‘Caffeine Operating System,’ plus smoker/grill-dad and burger breakdowns; he warns to check AI output for errors like a missing letter ‘E.’ Trend three is trinket / collectible-catalog designs — grids of rocks, seashells, flowers, fishing lures or coffees — producing a coffee order archive, a fishing lures catalog and his favorite, ‘My personality is coffee,’ which he says scales across tote bags, posters, mugs, t-shirts and even book covers. He then uses a custom GPT to generate the full listing (brand title, two bullet points, description) from the uploaded design, uploads the three designs to Amazon Merch priced at cost / low to rank, and shows checking trademarks with Merch Informer and Productor, cautioning against working around brands like Nike.

Key takeaways

• Turn a trend report into designs by feeding its examples to ChatGPT to get multiple concepts and prompts, each with an explicit ‘who’s buying it’ and ‘why it sells’ rationale
• Signal graphics should be loud, bold and readable for Amazon Merch thumbnails; Etsy suits broader bundles across posters, mugs, totes and shirts
• Blueprint / breakdown diagrams work for any passionate niche — coffee machines, smokers, burgers, pizza, ramen and sushi are the examples given
• Trinket / collectible-catalog layouts (rocks, seashells, flowers, fishing lures, coffee types) let one design scale across many product types
• Proof AI art before listing — the video catches a missing letter ‘E’ — upscale and remove backgrounds in Kittl, generate listing copy with a GPT, and run a trademark check in Merch Informer or Productor
