Our wedding is scheduled for August of this year. We are hopeful that we will still be able to have our wedding as we have planned but I have my back up dates already penciled in with all of our vendors. Thankfully, they have ALL been wonderful! In the event that I do have to cancel/postpone my wedding, I have the postponement cards all ready to go out. We will be postponing a year out. Is it necessary to resend a full blown formal invite at that time? Or can I ask our guests on our postponement card to go to our website and fill out a form that will give me an email address and send out a digital wedding invite the second time around?
