I like white and purple
which is green and black inverted

where do you edit Marth's Tiara? 

the easiest....prolly Peach and Marth
the hardest...prolly Toon Link because of all the +2 textures
and the most annoying: Ness, Lucas, Kirby, Jigglypuff because of their FS eyes

Found it~

and heres the link to stash:

hold on, I'll add a link. oh, and you can't keep the original three, you need to replace a theme that's already available.

quick note: you can only edit the 3 themes of the custom stages. not the custom stage itself.

I see...so is STASH a custom stage editor or a program that lets u customize existing stages?

yup. even the customs before you even make them.

you use STASH. sorta like ASH, but for stages.

I'm texture hacking Peach, and I'd like to know where I can edit the area between her gloves and sleeve puffs    
nevermind~ I got it~

crimson viper and sakura..... are just.... amazing @.@

depends on the character.
doesn't take me too long for a kirby/jiggs texture (about 40-50 minutes)
and just a little bit more for others.
but if it has a whole bunch of +2 or +1 textures, (like Toon Link)
maybe 2 hours or so...
