Costume help for when I go "green".

 A steampunk goblin would be pretty cool.

Green facepaint isn't reusable like a mask but masks can get really hot and bulky, you can always reapply green paint if you wipe it off but the mask might get so hot that you may not be able to tolerate it.
 

 
 yeah i might go with the face paint cause i want to wear http://www.medievalcollectibles.com/p-6303-empire-gentlemans-steampunk-coat.aspx
this which is nice and when i go healing as bard i take it off and start some dancning and stuff :P

if ya can spare the funds i'd go with a "living latex* mask...apply and it moves with you...

 ehhh not trying to appear so fancy on the face only ya know? plus its still a mask so it'll still
get hot, also ill need alot of time to put it on.

 I'd recommend using alcohol activated facepaint.  It's fairly simple to apply, does not sweat off easily and puts a green tinge on your skin rather than an opaque coat of greasepaint.
On the downside it is quite expensive and you'll need to get it from an online source or costume shop.

Gotta agree with Jenn here, alcohol actiavted is the way to go for all day facepaint.  I've got the grishal mask which is living latex but it still gets super hot.  I could probably wear it for a few hours at a time, but I don't think that I'd even want to consider wearing it all day in the heat.  On the up side, once we get past the August game, the heat really isn't an issue anymore =)

 alright I guess ill go with paint (alcohol) then and I know how I'll dress now so its all settled just gunna need to prep my gear and buy the things I need :). Thanks for the help guys & gals.

Anyone know where just individual colors of the alcohol paint can be purchased, rather than the entire palette?

 You can buy pre-mixed bottles of the various colors.  We got an extra green when we bought ours, because we figured that we'd use it the most.
