How To Use Midjourney To Make Mockups 🤯 For Print On Demand Ultimate Guide Revealed!

About this video

Martinez demonstrates how to create print-on-demand t-shirt mock-ups with Midjourney instead of using generic mock-up templates. The creator reports over six years in print on demand and over a million dollars in all-time sales. He prompts Midjourney with simple descriptions such as ‘mock-up for a plain black t-shirt on a wood floor’ or a plain white t-shirt hanging on a wall, swapping in shirt colors and backgrounds to suit a shop’s theme. He then builds holiday-themed versions — Fourth of July, Thanksgiving, Christmas and Easter backgrounds — advising sellers to name specific elements they want in the prompt, such as more pine cones, Christmas gifts, a barbecue cookout scene, a specific egg color, or an Easter bunny. From the results he upscales a chosen image or generates variations of it, saves it, and opens it in a photo editor on a transparent-background project sized for an Etsy listing, noting Etsy’s minimum 72 DPI resolution requirement. He mentions Pixelcut as a free option for upscaling AI images instead of stretching them. Finally he drags his design onto the shirt, resizes and repositions it until the placement looks straight and natural, and exports the finished mock-up as a JPEG for an Etsy shop, website, or ads — noting that in his example both the design and the mock-up were AI-generated.

Key takeaways

  • Prompt Midjourney with shirt color plus setting (‘plain black t-shirt on a wood floor’) and vary the background to match your shop theme or season
  • For holiday mock-ups, specify the exact props and elements you want in the prompt rather than accepting the generic themed background
  • Upscale or create variations of the best Midjourney result before saving it, rather than stretching a low-resolution image
  • Build the listing image on a transparent-background project at Etsy’s required resolution (he cites a 72 DPI minimum), then place and fine-tune the design’s position by hand
  • The same workflow serves Etsy listings, a personal website, and ad creative — one AI mock-up process covers all three
