obtaining addresses for thank you cards

I would just text them saying "I would love to send you a thank you card for your lovely gift, would you mind sending me your address" or maybe worded a little differently

FB/Call/Text is how I obtained addresses for invites, so I don't think it's tacky to do that for thank you notes. What would be tacky is FBing your thank you. Paper is definitely the way to go here.

I asked for addresses for our invites via email, text and Facebook message! However you get them is fine and I'm sure they will love to receive your thank you!

I think that's fine, it'll be how I get my addresses too.

Not tacky at all. I've also looked up names on the county auditor site but some might consider it creepy. *shrug*

That's not tacky, it's how I got addresses.

You can also ask Moms and Grandmas.

Just send them a message asking for thier address

Yikes you got married in March and you are just now thinking about this??

Gotta get on it, girl.

Call, text, email, ask family members. Do what you gotta do to get those addresses so you can send those hand-written thank you's out ASAP!
