Masked and ready to roll

For my process, masking is critical for having more freedom later. I use the selection tool (stylised ‘S’, top right), select Freehand, and trace the outer edge of the figure all the way around, finishing by tapping the grey dot at the starting point. I tap Save & Load in the bottom menu, and clear the selection by tapping ‘S’ again. Wash, rinse, repeat for any individual parts that will need their own colours.
