For example, here's this panel I had a lot of trouble with in the upcominc Chapter 5. I needed to find a way to make all the dialogue properly legible without masking the arches in the foreground. The solution I eventually came up with, as you can see above, was masking the balloons in such a way that it layers them behind the pillars and arches. I know it sounds simple, and it really is, but doing that digitally is a little more tedious and irritating than you'd think if you've never used Illustrator.
So I hope you don't mind this little self-indulgent diatribe. Maybe I helped inspire someone else out there get out of their head-bashingly irritating lettering dillema. I hope so. If not, this whole essay would seem incredibly arrogant.
