This is made from an envelope template PDF download available to members of the Letter Writers Alliance. I used a translucent blue vellum-type paper, printed from my trusty laser printer. Glue stick wouldn't hold the flaps closed properly, so of course I used glitter glue. A dragon sticker guards the contents.

I stamped the back of the letter, inside the envelope, so it would show through the vellum paper. The owl says "A note for you."
