HDoP Space mail art

This is about hand-drawn or painted mail art! Basically, you take a simple (white or uni-color) envelope and... draw or paint (or both XD) on it. In this case: something space themed. A night sky? Stars? Planets? The moon? A satellite? A space station? Either way: make it look pretty in your recipient's mailbox.

Please make sure to use paints that are waterproof, as envelopes may get wet in the mail system! If you use watercolors or other soluble paints, fix them with a suitable varnish.

Inside the envelope, include a nice message for your recipient. That can be a written postcard or greeting card, a letter, or similar. (It doesn't have to be space themed, though of course that doesn't actually hurt, either.) Don't forget to include your username and the name of the swap!

Mail this to your recipient.
