St. Patrick’s Day design tips

You now have plenty of ideas to start with. Pair them down with these quick tips to create St. Patrick’s Day designs people want to wear, share, and buy.

• Keep text bold and easy to read. Holiday shirts are a blast for parades, events, or group photos. Make sure your message really pops from far away with big, easy-to-read letters.
• Stick to one or two fonts. Too many typefaces make designs feel messy. Pair a playful headline font with a clean secondary font for balance.
• Use green as an accent, not overload. Wearing green is part of the fun, but fully green designs can feel heavy, especially if you’re planning to go full Irish from head to toe. Try adding green through text highlights, shamrocks, or borders instead. Don’t be afraid to take inspiration from existing t-shirts.
• Let short phrases do the heavy lifting. Clever one-liners and simple slogans work best for St. Patrick’s Day shirts. Keep the copy tight and memorable.
• Add small icons for extra charm. Shamrocks, lucky charms, rainbows, or subtle Leprechauns can enhance your text without taking focus away from it.
• Design with your audience in mind. Funny phrases work great for friends, softer messages suit families, and cute graphics shine on kids’ tees. Tailor your designs to who will wear them.
• Test on multiple shirt colors. Preview your design on light and dark tees to ensure it pops across different colorways.
