Well...Crap.

 So I spent like an hour messing around with Sai to get a nice looking 2 litre bottle of Diet coke to use as a template for my World record illustration. I've now hit that awesome snag were Ive realized that Sai doesn't really have the tools to select the Bottle without any white space, and when I take it into Photoshop it becomes kinda transparent. And there's still a white around it!

ON the other hand, the black background looks cool. I better not have to do this in Photoshop :(
