Oh! My chance! I made my own font!
And no one has ever commented on it but I think it looks hella good so I can't miss my chance to share.
I mean, sure it took forever and might not be perfectly weighted and the kerning can be weird at times but it looks more natural with my art style than any other font I could use. I think that beside hand writing everything it's the next best choice for many comics.
Other examples of writers that use their own handwriting, to great effect:
Also I used to typeset manga, so I can recognize really common fonts like CC Wild Words and Anime Ace and Manga Temple on sight and it honestly takes me out of the story for a second.
I don't think that's a common issue though.
