How We Printed 120 Custom T-Shirts for Githunguri Primary in 3 Days (Case Study)

In June 2026, Githunguri Primary School needed 120 custom T-shirts for their sports day - in just 3 days. This case study shows exactly how we delivered: the gang sheet layout we used, the pricing breakdown, the challenges we overcame, and the final result. Total cost: KES 78,000 for 120 shirts (KES 650 per shirt including design).

The Challenge

Grace Wanjiru, Head Teacher at Githunguri Primary School, contacted us on a Wednesday evening via WhatsApp. The school's sports day was on Saturday - just 3 days away. They needed 120 T-shirts in 4 different house colors (red, blue, green, yellow), each with the school logo on the front and student names on the back. Most printers in the area said it was impossible in that timeframe.

Grace had been referred to us by another teacher who had seen our work at a neighboring school. She needed someone who could deliver quality prints fast, without charging rush fees that would blow the school's budget.

The Solution: DTF Printing + Gang Sheet Optimization

We recommended DTF (Direct-to-Film) printing because:

• No minimum order per color (screen printing would require 4 separate setups, one per color)
• Works on any fabric color (red, blue, green, yellow all work with DTF)
• Fast turnaround - DTF doesn't require pre-treatment like DTG
• Vibrant, durable prints that survive 50+ washes (important for school uniforms)
• No setup fee - we only charge per print

The key to hitting the 3-day deadline was gang sheet optimization. Instead of printing each T-shirt individually, we arranged all 120 designs on 6 large gang sheets (20 shirts per sheet). This reduced print time by 70% and film waste by 40%.

The Gang Sheet Layout

Here is the gang sheet layout we used for this project. Each sheet was 22x12 inches (standard DTF sheet size) and held 20 designs:

We used our free Gang Sheet Builder tool to arrange the designs. The tool automatically spaces designs for optimal film usage and shows a preview before printing. This saved us about 2 hours compared to manual layout in Photoshop.

Pricing Breakdown

Here is exactly what Githunguri Primary paid. We provided the T-shirts, the printing, and the design work:

Per-shirt cost: KES 650 (including T-shirt, 2 prints, design, delivery). This is 35% cheaper than the next quote Grace received (KES 1,000 per shirt from a Nairobi printer).

The Process: 3 Days Start to Finish

Day 1 (Wednesday evening): Grace sent us the school logo (a JPEG) and the list of 120 student names. We used our free Background Remover tool to remove the background from the logo, then our Vectorizer to convert it to SVG for cleaner printing. We prepared the gang sheets and sent Grace a digital proof for approval - all within 2 hours of her first message.

Day 2 (Thursday): Grace approved the proof at 8am. We printed all 6 gang sheets by 2pm (6 hours of printing). Meanwhile, our supplier delivered 120 plain T-shirts in 4 colors (30 each of red, blue, green, yellow) by 10am. We started heat-pressing the transfers onto shirts at 3pm and finished all 120 by 8pm.

Day 3 (Friday): Quality check - every shirt inspected for print quality, alignment, and fabric defects. We found 3 shirts with minor print misalignment and reprinted them (free of charge). By 12pm, all 120 shirts were packed in labeled bags by house color and size. Our rider delivered them to Githunguri Primary by 3pm Friday - a full day before the sports day.

The Result

Grace sent us this message after the sports day: "hawa wasee walinisaidia sana. Niliwa-WhatsApp Wednesday jioni, by Friday T-shirts zote 120 zilikuwa ready. Print quality ni top sana, colors zilikuwa exactly kama design, na hata after kuoshwa mara kadhaa hazijafade. Bei pia ni fair ukicompare na wengi wa town. Nikifanya bulk order ingine, hawa ndio watu wangu."

Translation: "These guys helped me a lot. I WhatsApped them Wednesday evening, by Friday all 120 T-shirts were ready. Print quality is top, colors were exactly like the design, and even after washing several times they haven't faded. Price is fair compared to many in town. For my next bulk order, these are my people."

What We Learned

• Gang sheet optimization is critical for tight deadlines - it saved us 70% of print time
• Free tools (Background Remover, Gang Sheet Builder, Vectorizer) cut our prep time from 4 hours to 30 minutes
• Having a reliable T-shirt supplier who delivers same-day is essential for rush orders
• Quality checking every shirt before delivery prevents embarrassing defects at events
• WhatsApp communication (not email) is what Kenyan customers expect - respond within minutes, not hours
