Print On Demand — Tiny Pattern Repeats Or Big Ones?

The dilemma of a Print On Demand designer

I am relatively new to the idea of Print On Demand (as a seller I mean). In fact, I only opened my RedBubble shop in March of this year.

But I’m no expert in the design process.

I can do the basics on Photoshop, I’m quite proficient with Procreate and I can definitely use Canva. But I struggle with one concept and that is the idea of repeat patterns.
