Hey Guys... Got a couple custom stickers made for my st919 project. Got in contact with a guy here in Knoxville that will make small orders for you. He made me the ST919 stickers for $4 a piece, and they are reflective. he does this more for fun than to make money, So if you want anything made, give him a shout...
His website isn't much, but he does really good work.
a secret - diluted dish soap in a spray bottle. spray enough to make the surface wet, then you can move the sticker around. Vinyl stickers are porous and the water/soap mix will evaporate from behind the sticker. When it's dry it will be right there. Sweet eh?
now, if the sticker isn't vinyl I'm not sure how it would work. I print/cut vinyl on the side and that's how we do it.
