Well I don't have pics yet but here is my idea:
Have the Mexican blanket/serape as a table runner:
I ordered these maracas and I am going to put a pair or two on each table tied together by raffia.
And in the middle have a photo holder similar to this (I am in the middle of making them) hold up our table names (events from when we have been together such as: graduation, engagement, trips, College Days, Love at first site) and pictures of those times.
Finally there will be tea lights all around that. I have an image in my head I hope it all comes out right!
