Mailer Idea

Well this is just a concept I was exploring and I quickly made this up to see how it would look. This would be a printed on card stock with an acetate sheet on top. There would be a stain printed on the acetate cover and when you lift it would reveal the Sig Samuels logo. This would give the illusion that their dry cleaning will remove the stain. I need to figure out how to print on acetate and make it opaque as opposed to transparent. I may have to place a sticker on the acetate...not sure if thats going to look great.
