envelope in an envelope

This is fairly easy.

Take a smaller, yet postally usable envelope, you can make the envelope or have a store bought one and draw on it.

Leave the small one not addressed, so your partner can use it to send a swap.

Put it in a larger envelope and send it to you partner with a note stating user name and swap name at least. Please make sure the envelope for your partners use is not folded.

The smaller envelope is one I drew on, both sides, and will slip into the larger one.

Please no holiday themes. You can make the envelope from sturdy paper, drawn on one, decorate with washi or similar tapes, not one or two pieces, but real effort. Stickers can be used, but only to add to the art you have done.
