Return Addresses

Sounds like something you should ask the company that you ordered from. A return address is absolutely necessary whether it's printed or hand written.

So for STD's I wrote the addresses on the envelopes both address its going to and return address. You wouldn't believe how many I did receive back because I did something wrong to address. LOL. SO return address is def necessary. For the invitations I did a return address label and I wrote out every ones address's. I don't think it looks bad if you were to write the return address.

I did labels. Easy and tends to be cheap. I use them to seal the envelope too.

I ordered return address labels from Vistaprint. I think with shipping it was like $14 for 250 or something like that. I ordered 2 packs and it was enough for the STDs, invites, and thank you cards with some to spare.

Just put return address labels on them.

Depending on where you ordered your STD's from, most companies will accommodate changes even during production. Have you tried contacting their customer service to see if you can add on the return address?

I bought a stamp off etsy with my address and just used that on all the STD and I plan on using it on my invites as well!

I think it's necessary, if anything is returned or can't be delivered.

As PP have said definitely speak with the company if they can add that to the order or not. If not an option is to get pre made labels with the return address on it so you just have to place them on the envelope. That is what we did. We bought all our invites, rsvp cards and labels from vistaprint.
