I've always enjoyed lettering the sound effects on my strips, and this week's Team Toxic adventure has no less than three instances where the sound FX dominate the panels. I know some fans don't like comic sound effects because they think they're childish, but I've always considered them a vital part of humour comics, helping the reader to 'hear' the impact in their heads.
To me, designing the sound effects has always felt like a natural extension of the drawings. Computer fonts are brilliant of course, (particularly those by Comicraft) and I've used those too a few times, but I prefer to create a specific sound effect that suits the moment. I'm sure there are professional letterers (or 'balloonists' as DC Thomson call them) who could do a slicker job, but I prefer to do it myself where possible. I don't receive an extra fee for it but, as I said, I consider it part of the drawing. (Dialogue lettering is different of course. I'm paid extra for that when I do it, although these days it's mostly done by the in-house designers.)
Anyway, these are three panels from the latest Team Toxic two-pager, The Land of Living Farts, in the current issue of Toxic available right now!
