Canva Craft Tutorial: Create an Event Poster With AI

From Canva's homepage, choose More → Dream Lab, or open Dream Lab directly. It lives outside the design editor. Canva's Dream Lab instructions cover this route.

Check the model beneath the prompt. Our screen showed Canva Craft-1 2K already selected. If your screen offers a model menu, select Craft. Choose a 3:4 portrait ratio for the artwork; you will place it in an exact 1080 × 1350 design later. Check any usage notice before generating. Keep the style setting unchanged while you compare attempts.

If Craft is missing, check your selected account and workspace's AI access. Stop the Craft-specific exercise if you cannot select it; a result from another model would answer a different question.

For this example, the artwork needs a readable headline and a spacecraft approaching Mars. You will add the date, time, venue, and booking line as ordinary text in the editor. That keeps those details easy to change.

Paste this prompt into Dream Lab:

Create a portrait 3:4 illustrated travel poster for a fictional book club that meets on Mars.

Show a real science-fiction spaceship carrying the club toward an enormous rust-red Mars. Give it a sleek cream-colored hull, purposeful mechanical details, antennas, and bright blue engines. Broad observation windows reveal a cozy amber-lit library lounge with bookshelves and a few tiny silhouettes reading. It is a spaceship for people who love science fiction and books. Use a conventional spacecraft silhouette, not a ship shaped like a book or any other object.

The ship sweeps diagonally through deep midnight space toward Mars. Give the planet dramatic scale. Make the image feel like a collectible 1970s space-travel poster, with cinematic illustration, strong graphic composition, tactile print grain, and a limited palette of midnight navy, vermilion, warm ivory, and electric blue.

At the top, render these exact words once in large, clear ivory lettering:
MARS BOOK CLUB

Keep every letter distinct and inside the frame. Let the headline and spaceship each have room to breathe.

Reserve the bottom fifth as quiet midnight-navy space for event details I will add later in Canva. Keep the ship, planet, and engine trail above this area.

No other text, dates, logos, labels, watermarks, or real-world brands.

Generate a set of images. Save the prompt and keep the first results in Dream Lab's History before trying again. The Dream Lab workflow can return up to four options per prompt.

Choose the version with the clearest headline and enough room below the illustration. Look for a recognizable spacecraft, a dramatic red planet, and warm windows that suggest a reading lounge. Reject extra lettering, a crowded bottom section, or a cropped headline. Tiny interior details may need inspection at full size.

The ship should make someone want to join the trip. It also needs to leave space for information a reader can actually use.

Read the headline letter by letter. Look for MARS BOOK CLUB, once, with all three words intact. Check it at a small viewing size as well as close up.

If the lettering is unclear, return to the original prompt. Replace its headline directions with this block, keeping the rest of the brief and selected model unchanged:

Use plain, bold uppercase lettering for the headline. Show exactly MARS BOOK CLUB once. Keep every letter distinct and leave clear space between all three words. Add no other writing.

Generate again and compare the whole composition. A new generation can change more than the words. Keep the earlier result until the replacement passes the same checks.

Avoid spending several attempts on the same spelling problem. Use a text-free version and add the heading yourself when you need exact control:

Create a portrait 3:4 illustrated travel poster for a fictional book club that meets on Mars.

Show a sleek, cream-colored science-fiction spaceship approaching an enormous rust-red Mars. Its broad observation windows reveal a cozy amber-lit library lounge with bookshelves and tiny reader silhouettes. Use a conventional spacecraft silhouette, mechanical details, antennas, and bright blue engines.

Use cinematic 1970s space-travel illustration, dramatic scale, strong composition, and tactile print grain. Limit the palette to midnight navy, vermilion, warm ivory, and electric blue.

Leave the top quarter and bottom fifth as quiet midnight-navy space for text I will add in Canva. Keep the ship, planet, and engine trail in the middle of the composition.

Include no letters, numbers, logos, labels, watermarks, or real-world brands.

In that version, you will add the headline in Step 4. Both routes lead to the same finished poster. The text-free route also gives you direct control over the headline's font.

Keep the portrait design. Select the artwork and all four text boxes, then choose Group. Create a second blank design at 1080 × 1080 pixels using Custom size and paste the group into it. This approach does not require a paid resize feature.

Fit the group proportionally inside the square, then use Position → Center to center it. Match the page background to the artwork. Keep the whole headline, ship, and footer inside the page. Choose Ungroup in both designs so you can edit the date directly. Check the smaller supporting text at the square's actual viewing size.

Now test a realistic revision. Change the date in both designs to:

NOVEMBER 21, 2026

Only the date should change. Keep the title, time, reading room, and booking line fixed. The point of the editable details is to handle this update without generating another image.

Check both versions:

Use the editor's download controls to export a PNG of each design. Canva recommends PNG for graphics. Open both downloads, inspect the actual dimensions, and read every line again. Keep the editable Canva designs alongside the exports.

Stop at the files for this practice run. Do not publish the fictional event or order prints. You now have a checked portrait poster, a square version, and event details you can revise directly.
