well, I'd like to do it. My kiddos loved that our elf Ollie got so much Christmas mail from other elves around the world. I'll PM you my info. I think in the past we've gathered the following info:
Elf Name(s)
Complete Address as written on an envelope
and maybe when your elf arrives
email address
That's what I'll send and if you need more or something else, let me know.
I hope more people join in!
