I was thinking while shaping my armor dents.
When you heat up plastic with a heat gun and you are trying to push the end of a broom handle into just the right spot while holding around it you tend to scorch your fingers pretty good!
So far, on top of this, I have slipped with an X-acto Knife (I don't think I have to elaborate on that for any true hobby person) and stabbed my self several times with a needle (while sewing...not for recreation)
Lets hear some Fett costuming injuries. I know I'm not the only one. (I hope)
