Secret Letter ATC

What does your letter contain?

For this swap, you must make an ATC that features an envelope. You have to be able to open the envelope in some way and see the contents.

It could be an whole envelope, opening up at all corners to reveal a love letter. It could be a small letter in the corner, hiding some secret documents. Be creative! Make something you're proud of, that others would want to see! Spooky? Fantastical? Sparkly? Elegant?

Standard rules apply: 2.5 x 3.5 inches for your ATC's. No sticker slapping, and decent backing cards, please. No recent/unexplained 1's or 5's, and all swappers must have a rating of 4.8 or more. Newbies can participate, but they have to have well-filled-out profiles. I will be checking! Experience shows these usually end up being a bit bulkier than your usual ATC - so be prepared :)

So - what secrets does YOUR letter hold?
