How it works

Design your own custom t-shirt online, then let a real print shop make it

Power Graphics' Design Studio is a free online t-shirt design tool from a family-run screen printing and embroidery shop in Derry, New Hampshire. Pick a real garment from our catalog (Port & Company tees and hoodies, Port Authority polos, caps and totes), choose any color, and build your artwork with 26 fonts, curved text, clip art, shapes and your own uploaded logo or photo.

Switch between screen printing, embroidery and DTF full-color modes and the tool tells you what will print well: ink-color counts for screen printing, stitch-friendly sizes for embroidery, no limits for DTF. Save your design to a free account, download a preview, and send it to us for a quote. Nothing is charged online; a real person reviews every design, confirms sizing and placement, and replies within one business day.

Who uses it

  • Schools and PTOs making spirit wear and class shirts
  • Youth sports leagues and teams in Derry, Londonderry, Windham, Salem and across southern NH
  • Small businesses that need uniforms, polos and promo tees without hiring a designer
  • Fire and police departments, nonprofits, fundraisers and events
  • Family reunions, bachelor and bachelorette parties, memorials, with no minimum on DTF and embroidery

Design tool FAQ

Is the t-shirt design tool free to use?

Yes. Designing, saving and downloading a preview are free. You only pay when you approve a quote and we print your order.

Can I upload my own logo or photo?

Yes. Upload PNG, JPG, WEBP, GIF or SVG files up to 15 MB. Vector files (SVG, AI, EPS, PDF) print sharpest for screen printing and embroidery; a 300 dpi PNG with a transparent background is ideal for DTF.

What is the minimum order?

Screen printing starts at 12 pieces per design. Embroidery and DTF have no minimum, so a single hoodie is fine.

How accurate are the colors on screen?

Garment mockups use the manufacturer's product photos and are tinted to the shade you pick, so they're close, but monitors vary. We match ink and thread to your approved proof before printing.

Do you ship outside New Hampshire?

Yes. Pickup at our Derry shop is free, we deliver larger orders in southern NH and the Merrimack Valley, and we ship nationwide.

Can I design the back of the shirt too?

Yes. Use the Front / Back switch at the top of the studio. Both sides are saved with your design and included in your quote.
