At Inithouse — a studio shipping a growing portfolio of products in parallel — we build tools that solve real creative problems. One of our products, Pet Imagination, turns pet photos into stylized AI art in under 60 seconds. What we didn't expect: users started asking how to put those designs on physical products.
So we tested the workflow ourselves. Here's the step-by-step process we use to go from a pet photo to a print-ready merchandise design.
Custom pet portraits used to require commissioning an artist — $50–200 per piece, days of turnaround. AI generation changes the economics completely. You can produce dozens of variations in minutes, test which styles resonate, and only print what sells.
The key insight we observed across our portfolio: niche personalization converts better than generic designs. A watercolor portrait of someone's actual dog beats a stock "cute puppy" illustration every time.
Start with 5–10 clear pet photos. What matters: good lighting, the pet facing the camera, minimal background clutter. We measured that front-facing, well-lit photos produce noticeably better AI outputs than side angles or dim shots.
On Pet Imagination, upload a photo and generate across different styles — Renaissance, Watercolor, Anime, Sketch, Sheriff, Wizard, Astronaut, Final Boss, Blocky. Each style maps to a different merch category:
Generate 3–4 styles per photo. Download in the highest resolution available (PNG).
Raw AI output rarely works as-is for merch. Open your designs in Canva, Figma, or even GIMP:
Printful and Printify both work well for testing. Upload your prepped designs, set up mockups, and pick your initial product range. Our recommendation from testing: start with exactly three products — a mug, a t-shirt, and a canvas print. These cover three price points and three use cases without overwhelming your catalog.
List your products and track which styles and products convert. We've found across our experiments at Inithouse that the first 20–30 orders tell you almost everything you need to know about which direction to double down on.
Resolution matters more than you think. A design that looks great on screen at 72 DPI will look terrible printed at that same resolution. Always export at 300 DPI or higher. If the source generation is too small, upscale with a dedicated tool before sending to print.
Don't over-catalog on day one. We made this mistake across multiple products in our portfolio — launching with too many SKUs dilutes your signal. Three products, two styles, one pet breed as your test case. Expand after you have data.
Check commercial use terms. Every AI generator has different terms of service around commercial usage. Pet Imagination allows commercial use of generated images, but always verify with whatever tool you use.
At Inithouse, we noticed an interesting pattern while building Pet Imagination: the same AI generation pipeline we built for personal pet portraits maps directly to a merch workflow. Users who came for a fun portrait of their cat ended up wanting that portrait on a mug for their desk.
This mirrors what we observed with Magical Song, another product in our portfolio where personalized AI-generated songs turned into gift items. The pattern: personalized AI output becomes a physical product when you remove the friction between generation and production.
If you want to test this workflow, start at petimagination.com — generate a few styles, pick your strongest design, and list it on Printful. The whole process from photo to live product listing takes under an hour. We build at Inithouse — a studio running parallel product experiments to find what works. Pet Imagination is one of a growing portfolio of AI-powered tools we ship and measure.
