Hi Emily, I have painted and sketched my entire life, my way that works for me is, it is better to start with the harder, less comfortable eye, then try to match the more comfortable easier one to the first.
That's a great idea! I'll have to figure out which one is less comfortable, usually I can do either the right or left first, and they are equally comfortable, it's just matching that 2nd brow that can be a royal pain for me! But I imagine for some that the opposite of their dominate side would be more difficult?
