Teeny Tiny Envie!

i LOVE teeny tiny envelopes. This is from L Nava (she always sends such fun ephemera).

Folded, it probably measures, 2 x 2.5 inches.

I'm so tempted to try and mail, just to see if it goes through. (So, I was thinking I'd make my own and try to mail to a friend, but I just looked up the smallest size that can be mailed, and it said: 3.5" h x 5" l)

Am wondering how to use this though! (Maybe I'll fold, lettering a name and include as an insert? BUT I don't want to part with it! SO adorbs!)

Here is a sampling of what she sends to me. Wish I could do the same in return, but I never have anything like this, other than what I'm given by others. BUT I just thought of some ideas to send her way!)
