When applying iridescent or frosted polish how should the strokes be to the sidewalls?

When applying iridescent or frosted polish, the strokes should be smooth and even, extending from the center of the nail towards the sidewalls. It's important to avoid overloading the brush to prevent pooling at the edges. Use a light hand and ensure the polish is applied in thin layers for better opacity and a more polished finish. Finally, be careful not to touch the sidewalls directly to maintain a clean look.
