Frequently Asked Questions
What does "organic cotton" mean?
Organic cotton is grown and processed without synthetic chemicals, genetic modification, or harmful dyes. It is environmentally friendly, conserves water, and ensures better working conditions—certified according to standards such as GOTS. (Of course, this applies only to products that are explicitly made from organic cotton.)

How It All Began
The idea for Studio Sonntag came about when we wanted to do a favor for a mutual friend. We designed a personalized T-shirt for him, his wife, and each of his children, each with matching designs. The enthusiasm and gratitude we received in return inspired us to make this opportunity for personalized design accessible to everyone.
We hope you enjoy browsing and designing—and we hope our products bring you and your loved ones just as much joy!
