Then cut it out and simply leave it in water for a minute.
Then slide it onto your Wii...and position properly getting any air bubbles out.
I sprayed lacker over the areas when it had dried.
I got the Wii template for the console shape on www.decalgirl.com
Simply loaded this into photoshop and imported my own graphics, resized to suit.
Tip for newbies using lacker: i.e. ME......... Spray on to surface face down. I held the wii upright and ended up with some drip lacker markings :-( Hard to see 2 feet away but on close inspection you can see drip markings.
