You are planing your wedding, and want to incorporate chocolate in your ceremony because you met over chocolate;  but your wedding is outside in July, so you assume because of the heat that this won't work.  You love the outdoors, you and your partner hike, work in the soil, saw and stack wood together and you wonder if somehow you can bring this into your wedding ceremony with more than just words.  You are animal lovers and own a dog, you want him involved in the ceremony but do not believe this can happen.    As a wedding officiant and celebrant who creates customized ceremonies my response is-of course we can!   Wedding rituals are meaningful if they speak to your heart, reflect you story as a couple and honor that which you feel is important in your life.  They offer a rich way in which you can celebrate your passions, beliefs and values and also create new traditions for the future.  There are many lovely rituals that are steeped in tradition and used for wedding ceremonies, but you can also create your own.
Here are some quick tips: 

• Understand what the overall message you wish to relay through a ritual is - do you want to honor how you met? Are there important activities you do together that join your lives?  Do you have shared commitments that are important as you join together in marriage?  Do you wish to honor the community of people that are celebrating with you? Do you want the community to be actively involved in your ceremony?
• Whatever the overall message is, as you design your ritual keep it simple and clear. 
• Test out the ritual with others to see what works and what needs to be tweaked.
• Make sure there is an explanation of the ritual and the meaning it has for the two of you during the ceremony.

Two last hints: when you think you can't do something, or it won't work, turn these statements into questions and ask How might it work? What needs to happen for it to work and be included? 
Finally - Have fun!
