Design a Football Kit With AI: How My Son's Design Won the Camp

Step-by-step process

Step 1: Gather your images

Before opening Nano Banana 2, collect what you need. Download or photograph your organisation's logo. Find clear images of the reference jerseys your child wants to use. Keep them in one folder. This saves time once you're inside the tool.

Step 2: Generate the kit outline

Open Nano Banana 2 via Higgsfield and upload the Tekkers logo. Use this prompt, adapting it for your own club:

I would like to have an outline of a football kit which should have jersey, shorts and socks. The jersey should have this crest. There should be no other colours.

This generates a clean, blank kit template with the crest in place. No fill. No shading. Ready to colour.

💡 Parent Insight: If grey shading appears, add "black outline only, no fill, no shading, white background" to the prompt. The more specific the instruction, the cleaner the result.

Step 3: First design, free colouring

Print the outline and hand it to your child with no instructions. Let them colour it in freely. No pattern reference. No rules. This gets them engaged and gives them one complete design before the pattern steps.

Step 4: Apply your first jersey pattern

Mateo chose the Arsenal third kit for his first pattern. He loved the geometric design. Upload the blank kit outline and the Arsenal jersey image together, then use this prompt:

Could you now add the pattern from the Arsenal jersey to the jersey in the outline image. There should be no colour in the outline image. The outline jersey should only have the pattern from the Arsenal jersey and nothing else - do NOT include the Emirates sponsor, the Adidas and Arsenal crest. Everything about the outline image should stay the same except for the pattern.

‍

Result: The geometric pattern transferred onto the outline. No Emirates sponsor. No Adidas logo. Tekkers crest stayed in place. Worked on the first attempt.

💡 Parent Insight: Name every sponsor and badge you want excluded. "No logos" is too vague. Nano Banana 2 responds to specific names. The more you name, the cleaner the result.

Step 5: Apply a second jersey pattern

Mateo then picked the Ireland away kit for his second pattern. Upload both images again and use this prompt:

Can you recreate the pattern from the jersey on the right onto the outline jersey in image 1. I don't want you to include the sponsor (Sky) and I don't want the Castor logo. I want you to use the Tekkers logo from the outline jersey in image one. Maintain the pattern from the real jersey and put it on the outline jersey but without any colours - only transfer the pattern without any colours. And no dark greys. Just lines for the actual pattern so it can be coloured in for a kids activity.

Result: The Ireland diagonal stripe pattern transferred onto the outline. Tekkers crest held position. Pattern rendered as line work only, ready for colouring.

Step 6: Child colours in all designs

Print each patterned outline and let your child colour them in different schemes. Mateo ended up with several distinct designs from the same base template.

‍

Step 7: Submit and compete

Mateo brought his designs to camp on Tuesday. His teammates voted his design the best on the PSG team. It then competed against all the other teams in the full camp vote. He won. His design is now being considered for the real Teaching Tekkers kit next season. He came home buzzing.

What worked

The blank outline prompt

The "no colours" instruction produced a clean colouring template on the first attempt. No iteration needed. The kit came out with just enough detail to be recognisable but simple enough for Mateo to colour any way he liked.

Lesson: State what you don't want, not just what you do. "No colour, no fill, no shading" beats "just the outline."

Pattern transfer with reference images

Both jersey pattern transfers worked on the first try. Uploading a clear reference image and being specific about exclusions made the difference. Mateo got clean line-work patterns he could colour in any scheme.

Lesson: Give Nano Banana 2 a real reference image alongside the prompt. Description alone produces inconsistent results.

Keeping the child in control

The AI handled the technical parts. Mateo handled every creative decision. Which jersey to reference. Which colours to use. Which design to submit. His ownership of those choices made the result feel genuinely his.

What to watch out for

Unintended shading in the outline

Nano Banana 2 sometimes adds subtle grey shading even when asked for no colours. If this happens, add "white background only, no shading, no fill, black outline lines only" to your prompt.

Time cost if this happens: One additional generation, about 3 minutes.

Sponsor logos appearing in the result

Generic exclusions like "no logos" are less reliable. Name each one specifically: "do NOT include the Emirates sponsor, the Adidas logo, the Arsenal crest". This consistently worked for us.
