Ideas Plz! (day fifty one)

So, I was thinking of having a selling table at Lubricus. It's just a two hour craft fair, so I won't need to bring a ton of shwag, but I'd like to know, What kind of stuff should I sell there?

Stickers?
T-shirts?
Pins?
Car decals?
Prints of my art?
Iron ons for t-shirts?

Of course, I haven't left myself much time in which to prepare (as is my Modus Operandi)(sp), but if you were at a craft fair, what type of stuff would you be tempted to buy? And what kind of prices do you think would be fair?

TIA!
