20 AI Tumbler Designs in 20 Minutes?! (Kittl + Etsy Demand Test)

About this video

He demonstrates making tumbler designs quickly with Kittl AI, checking demand on Etsy with EverBee first. He browses Etsy picks/star sellers for patterns already selling on other products — notably a ghost reading a book / books-and-library theme, Halloween/pumpkin ideas, and funny golf tumblers — and uses signals such as ‘in carts’, added carts, all-time and monthly sales and revenue shown by EverBee to judge demand, discarding ideas where sales are not there. He uses ChatGPT to turn a reference image/concept into a prompt, generates images in Kittl (choosing Ideogram models), removes backgrounds, upscales/vectorises, and refines the ghost design with autumn leaves, pumpkins and a witch hat, scratching the golf idea. The core speed technique is Kittl smart boards / flows: one main board concept is varied into many themes — he counts over 20 designs in total — including animals reading books (sloth, goose, donkey, rabbit), and drink/cup patterns in strawberry smoothie, pumpkin spice, watermelon, pizza, cherry, sushi, burrito, Halloween, Christmas and Thanksgiving versions. He puts designs on tumbler, mug and person-holding-mug mockups for social media, shows downloading single or all artboards, and mentions using a print-on-demand service such as Gelato, which he says integrates with TikTok Shop, Amazon, Etsy, Shopify and others and prints/ships on sale while the seller handles customer service. He closes claiming the prompts, over 20 designs, mockups and demand check were all done in under 20 minutes.

Key takeaways

• Research on Etsy first with EverBee: look for in-cart/add-to-cart counts, monthly and all-time sales before designing
• Transfer proven concepts from t-shirts to tumblers rather than starting from a blank page
• Use ChatGPT to write/improve image prompts, then generate and clean up designs in Kittl (background removal, upscale, vectorise)
• Use Kittl smart boards to spin one main concept into 20+ themed variations in minutes
• Create mockups in Kittl and fulfil via a POD service such as Gelato instead of holding inventory
