30 Midjourney Prompts for T-Shirt Designs

A print-on-demand seller uploaded 61 designs last quarter. Four sold. The winners were not the cleverest concepts; they were the ones printed on a heather gray tee that looked like something you would buy at a park visitor center after a long hike. The losers were beautiful images that fell apart on fabric: gradients that banded, tiny details that vanished, and mockup text that read like gibberish. POD is a print business with an art hobby attached, and the print constraints have to come first.

The thirty prompts below are built for that order of operations. They start with a design niche, move to text and typography problems, then to file preparation for actual printing, and finish with variations and mockups. Every prompt assumes vintage national park artwork as the working example, but the structure transfers to any niche. For the parameter vocabulary that controls mood and rendering, see the Midjourney style parameter guide.

How to Use This List

Add --v 7 and --style raw to most of these unless a prompt says otherwise. Replace the bracketed variables and keep the composition terms intact, because those are what make a design printable. A useful habit is to generate at least four variations per idea with --ar 4:5 for the artwork itself, then handle mockups separately. If you need the artwork placed on a garment for a listing image, the product mockup prompt covers that step properly.

Vintage National Park Designs

1. Classic park badge. The workhorse layout that sells year after year.

vintage national park badge emblem, [PARK NAME] scenery, circular patch composition, pine trees and mountain ridge, retro 1970s US park service poster style, flat screen print colors, cream background, thick outer ring border, high contrast, no text, centered, --ar 4:5 --v 7 --style raw

2. Retro sunset silhouette. Simple shapes survive printing on dark fabric.

retro sunset over [LANDMARK], bold silhouette layers, three-color palette of burnt orange, mustard, and deep teal, vintage screen print aesthetic, flat shapes no gradients, centered composition with generous negative space, --ar 4:5 --v 7 --style raw

3. Vintage travel poster. The mid-century look buyers associate with national parks.

1930s WPA national park travel poster illustration of [PARK], dramatic landscape, limited four-color screen print palette, visible ink texture, strong foreground frame of pine branches, wide landscape composition, no lettering, --ar 4:5 --v 7 --style raw

4. Minimal line art. Clean edges print well at small sizes.

minimal single-line illustration of [PARK LANDMARK], one continuous contour line, thin even stroke weight, small solid accent shape in [COLOR], lots of white space, modern outdoor apparel graphic, no text, --ar 4:5 --v 7 --style raw

5. Distressed screen print. A texture that hides small print defects.

heavily distressed screen printed graphic of [PARK SCENE], cracked ink texture, off-register color layers, faded vintage tee print, muted earth tones, rough edges, aged garment feel, centered, no text, --ar 4:5 --v 7 --style raw

6. Topographic map motif. Works for hikers and looks technical without being busy.

topographic contour map of [REGION], clean thin contour lines, one highlighted route line in [COLOR], subtle elevation shading, vintage map paper tone, rectangular composition, no labels or numbers, --ar 4:5 --v 7 --style raw

7. Night sky over the park. Good for dark garment blanks.

night sky over [LANDMARK], star field and milky way, deep navy and black silhouette foreground, small warm campfire glow, vintage astronomy print aesthetic, high contrast for dark shirt printing, no text, --ar 4:5 --v 7 --style raw

8. Ranger patch style. Sells as a set across multiple parks.

national park ranger shield patch, [PARK] landscape inside a shield outline, embroidered patch look with visible stitching, three thread colors, flat vector shapes, symmetrical layout, no readable text, --ar 4:5 --v 7 --style raw

Handling Text and Typography

9. Design around a text gap. Reserve the space, then set type yourself.

vintage [PARK] illustration designed with an empty horizontal band across the lower third reserved for typography, artwork only above the band, symmetrical, flat screen print colors, do not render any letters or numbers, --ar 4:5 --v 7 --style raw

10. Curved banner placeholder. For park names that need an arc.

retro patch design with a blank curved ribbon banner across the middle, empty banner with no lettering, pine forest and mountain scene above and below, three-color vintage palette, thick outline, --ar 4:5 --v 7 --style raw

11. Stacked wordmark space. Two lines of type, no guessing.

emblem artwork with two empty stacked rectangular placeholders on the right side, blank label areas with no text, landscape element on the left, vintage outdoor poster style, flat colors, --ar 4:5 --v 7 --style raw

12. Force empty text zones. For when the model keeps inventing words.

[PARK] vintage tee graphic, all text areas deliberately left blank, no letters, no numbers, no symbols, no watermark or signature, only landscape illustration and decorative shapes, --ar 4:5 --v 7 --style raw

13. Render type as shapes only. When you want the look without legible words.

vintage poster for [PARK] where all typography is rendered as abstract geometric shapes and lines suggesting text, unreadable letterforms, purely decorative, landscape illustration dominant, --ar 4:5 --v 7 --style raw

14. Text-safe composition rules. A reusable instruction block.

Create a t-shirt graphic of [SUBJECT] following these rules: no legible text, all lettering zones empty, subject centered with at least 15 percent margin on every side, maximum four flat colors, no gradients, no photographic elements, --ar 4:5 --v 7 --style raw

Getting Print-Ready Files

15. Flat color separation look. Fewer colors means cheaper and cleaner printing.

flat spot color illustration of [SUBJECT] for screen printing, exactly three solid ink colors, no gradients, no transparency, hard edges between color areas, white background, --ar 4:5 --v 7 --style raw

16. One-color version. The cheapest design to print, and often the best seller.

single color monochrome graphic of [SUBJECT], one ink on white, heavy silhouette with clear negative space detail, no halftones, no shading, bold unmistakable shape readable from ten feet, --ar 4:5 --v 7 --style raw

17. High contrast for dark garments. Light inks on black need thicker forms.

high contrast light-on-dark t-shirt graphic of [SUBJECT], cream and pale gold ink on black, thick outlines and solid shapes, no thin lines under 2mm, no fine gradients, vintage outdoor brand feel, --ar 4:5 --v 7 --style raw

18. Isolated on transparent background. A checklist item before any upload.

[SUBJECT] as an isolated graphic on a pure flat white background, no shadow, no texture, no background scenery, crisp edges suitable for background removal, centered, generous margins, --ar 1:1 --v 7 --style raw

19. Clean vector aesthetic. Fewer surprises during upscaling.

clean vector-style illustration of [SUBJECT], smooth uniform outlines, flat fills, no texture or brush strokes, geometric simplification, Adobe Illustrator poster look, plain background, --ar 4:5 --v 7 --style raw

20. Halftone texture. Adds depth without adding a color.

vintage halftone dot texture illustration of [SUBJECT], visible dot pattern for shading, single ink color plus white, retro newspaper print feel, bold shapes, --ar 4:5 --v 7 --style raw

21. Large format detail. For prints that go on the full chest area.

Niche Variations and Mockups

22. Kids version of a proven design. Same art, simpler shapes, softer palette.

simplified children's version of a [PARK] landscape graphic, rounded friendly shapes, soft pastel vintage palette, fewer details, thick outlines, cheerful without being cartoonish, no text, --ar 4:5 --v 7 --style raw

23. State park variant. Extend a winning design to a new market.

redesign the same composition for [STATE PARK]: keep the badge structure, flat three-color palette, and vintage screen print style, but change the landscape features to [LOCAL FEATURES], no text, --ar 4:5 --v 7 --style raw

24. Hiking sub-niche. Slightly different buyer, same visual language.

vintage tee graphic celebrating long distance hiking, trail winding through [TERRAIN], small hiker silhouette, topographic elements, three-color palette, badges-and-banner composition with no lettering, --ar 4:5 --v 7 --style raw

25. Camping and van life variant. Broader audience than a single park.

27. Flat lay with context. Sells the lifestyle, not just the garment.

flat lay product photo, folded navy t-shirt with a vintage park print, placed on a canvas backpack with a compass and a paper map, muted earth tones, soft daylight, styled but uncluttered, --ar 4:5 --v 7

28. Embroidered patch variant. A higher price point for the same art.

embroidered iron-on patch of a [PARK] landscape, visible satin stitching, thick merrowed edge, five thread colors, slight fabric texture, photographed on a plain background, --ar 1:1 --v 7

29. Die-cut sticker version. Same design, zero new art cost.

die-cut vinyl sticker of a vintage [PARK] emblem, thick white border following the silhouette outline, glossy surface with a soft highlight, placed on a laptop lid, shallow depth of field, --ar 1:1 --v 7

30. Build a matching five-park set. Consistency is what turns one sale into a collection.

create a consistent series of five vintage park emblems for [PARK 1], [PARK 2], [PARK 3], [PARK 4], and [PARK 5]: identical badge geometry, identical three-color palette, identical line weight, only the landscape content changes, flat screen print style, no text, --ar 4:5 --v 7 --style raw

Bonus Techniques

Four things that separate sellers who scale from sellers who upload sixty designs and sell four. First, build the set before the single: prompt 30 costs nothing extra and converts browsers into collectors. Second, never let the model render the words, because letterforms come out wrong and reprints are expensive; reserve the space with prompts 9 through 12 and set type in a design tool. Third, test every design in one color before you pay for a four-color separation, since a silhouette that reads in one ink will read in four. Fourth, if you want a wordless emblem system instead of scenery, the logo prompt approach is a better starting point than a landscape prompt.

Sources & Notes

These prompts were developed for a print-on-demand seller building a vintage national park line, so the constraints reflect real screen printing and direct-to-garment limits: limited inks, no thin lines, no gradients, and no generated text. The artwork prompts and the mockup prompts are intentionally separate; the first produces a file you print, the second produces an image you list.

Two cautions. Midjourney does not output true vector files, so prompts 19 and 20 give you a vector-like look rather than a scalable path; run the result through a vectorizer if your printer requires one. And always check that generated artwork does not reproduce a protected park service emblem, brand mark, or another seller’s design before you upload it to a marketplace.
