You know, I was considering skipping this one entirely, just to tick off Mike, but I know a lot of people have been wondering about this, so I figure in spite of my desire to tweak him, I’d help other folks out. 
I’m going to cover a few different ways to produce the desired speech balloons, using a few easier ways to do it first, and then finishing off with my own personal way. Some of these methods require specific software, though some of it is easily attainable. To demonstrate the Speech Bubble Creation methods, I’m going to use an image that I am planning on putting into a review coming up shortly. I’ll try each method and let you determine which one works best.
