The computer screen does not show how colorful this really is. The only disadvantage to sending a letter this way is that if you use vintage stamps like I did, they don't stick very well to the plastic. I had to secure the edges with packing tape, leaving the body of the stamp alone so that the post office can postmark the stamps. And of course, you know that everyone who sees this envelope during its journey will try to read what it says. So, if you're a private person or you have some juicy secret to share, than I suggest leaving that for the middle pages so no one can intrude upon your privacy. Of course, you could always cover up the writing with stickers and washi tape.
On the last piece of painted paper I wrote a couple of quotes. This is the back of the envelope. You know, it still makes it fun, but again, I'm not revealing any secrets to the universe. Yeah, the good stuff is in between. Don't you wish you could read it all?
So make some art, write a letter on it and send it in a clear envelope so you can share your creation with the postal workers. I used a 5 x 7 postcard sleeve for the envelope.
Have a fun and creative day!
