SE: Mail Art for Beginners - Tree(s)

All skill levels welcome - no artistic skills required - just have fun and do your best!

Take a plain, mailable size envelope (purchased or handmade, white or coloured).

Turn the front of the envelope into tree themed mail art (meaning that tree(s) must be prominent) using any material and any technique you like except digital or sticker slapping. No more than 3 stickers may be used.

Doing the back of the envelope is not required.

Inside, include a friendly note to your partner about trees (more than 2 or 3 sentences please).

Have fun!
