Sure, think of it like a grid of squares on a napkin. If each square is wide enough that your eye can rest on one without feeling cramped, it’s soothing. If the squares crowd each other so the eye can’t breathe, it feels claustrophobic. So a quick rule: keep the spacing at least as wide as the width of the motif itself. Then you can tighten it a bit if you need more rhythm, but don’t let the gaps shrink below that; the eye will start to sweat. It’s all about giving each element room to breathe while still holding the pattern together.
