This is the order of our ceremony:
Welcome
Reading
Small Speech About Us As A Couple
Reading
Sand Ceremony
Reading
Vows
Echange of Rings
Blessing Over the Engagement Ring
Pronouncement Of Marraige
Kiss
Breaking of the Glass
What I would reccomend is getting to know your officiant well before the ceremony, if in person or through email or phone conversations. This will enable them to write something very sentimental about you as a couple. Our officiant is in the family, so obviously she knows us very well.
Also, try to look for readings that you could do. Poems that you love, saying that you love, song lyrics that are appropriate to your marriage, or religious verses (if you're doing a religious ceremony). Then, enter them all into a word document. Try to put all the readings in an order that actually flows/makes sense. This was probably the most difficult part for us bc we wanted to include a lot in the ceremony, and they were all things that meant a lot to us, but didnt flow naturally. But with a lot of work, you can get the entire ceremony to flow properly.
Good luck!
