So, thanks to all of your great stories and suggestions about developing a persona, I've come up with an idea I really like, and am hard at work making it happen.
I made up a "business card" for exchanging emails, etc., at any steam gatherings I might make it to...
The picture is by Gibson, and it's called "Serious Business" - I couldn't resist using it.
Hopefully I'll have pictures of my outfit and accessories to share soon!
