A straight repeat arranges pattern tiles in aligned rows and columns. The edges line up directly, creating a regular grid.
A half drop repeat offsets every second row by half the height of the pattern tile. This creates a more staggered arrangement that is often used for floral, botanical and other organic designs.
Both repeat styles can work beautifully. The best choice depends on the composition of your artwork and the effect you want to achieve.
Tip: Always check that the edges of your original pattern tile connect seamlessly. A repeat preview helps you inspect the overall flow, but it does not replace checking the tile edges themselves.
