I've just recently gotten into Adobe Illustrator and am having trouble maintaining consistency when tracing various shapes that portray a stroke-like effect.
As an example I would like to point out this gray outline located around the purple filling:
As you can see, the width of the gray outline is clearly not consistent. How would I go about maintaining consistency when tracing similar images?
An idea that I had was to copy the bigger shape, and then simply size it down using the same center-point. Whilst this works sometimes, it doesn't on some more complex shapes.
