Your rosetta is decided before the wiggle.

Begin the base while there is still room in the cup, rather than waiting until it is almost full.

Once the pour begins, keep every movement purposeful. Avoid repositioning that interrupts the pattern.

Begin with the cup tilted. As it fills, bring it level without a sudden change of angle.

Prepare an even surface before drawing. The rosetta begins after the canvas is ready.

Let the crema stabilize, then continue into the pattern without adding extra movement.
