The 4 S’s of sending your invitations (stuffing, stamping, sealing and sending) simplified and my list of essential supplies to get the job done right.

Stuffing:

Place the cards from smallest on top to largest on bottom so that all cards will be seen when your guest removes it from the envelope.
Remember to include a stamp on the response card envelope. Most response card envelopes will need a forever stamp, but if your response card has anything 3-D (ribbon, wax seal, etc) or is a square it will need more postage than a forever stamp. More on stamps below…

Stamping:

Most wedding invitations will need “Two Ounce” or “extra postage” (more than a forever stamp) for the outer envelope. Please always confirm the amount of postage needed with the post office you plan to send the invitations from before buying your postage. I have learned it can vary from post office to post office.
As I mentioned above, please remember to include a stamp on the response card envelope. Most response card envelopes will need a forever stamp, but if your response card has anything 3-D (ribbon, wax seal, etc) or is a square it will need more postage than a forever stamp.

Sealing:

The best way to seal the envelopes is to use Glue sticks or “Dab-N-Seal” adhesive! No licking required! (Affiliate links included)

Sending:

Double check all postage required with the post office you plan to send from!
You can ask for “Hand Canceling” so that they won’t go thru the machine, but honestly I think they all go thru the machine anyway now. That is what I have been told and found to be true, unfortunately!
