I ran across this idea recently on a blog and LOVED it! Looking for something different to do for your invitations or save the dates that require very little effort from you with a maximum impact? Telegram Stop has now made it easy to send old fashioned telegrams in bulk! you can download their excel document, fill it out with the names and addresses on your guest list and send out beautiful telegrams with a killer envelope for $3.75 a person (bulk pricing). Great idea for a budget invitation, plus they practically do all the work for you (no addressing envelopes, putting invitations together, printing or postage stamps required).
Love this idea!
