Our ceremony will take place at sunset on Siesta Key Beach. 
I'm working with A Dream Wedding in Paradise and they have many ideas for beach decor for the ceremony!

I got this picture off a different site because I loved the idea of the lighted tiki torches.  For the alter area, I like the bamboo arch better though.

Sand Ceremony

This is the sand we'll be using during the sand ceremony.  Bought these from exclusivelyweddings.com.  The colors match ours very closely!
