Ideas to build some decorations or functional for my wedding reception

Hi All
I am due to get married next year, and we are having the reception in a marquee. My fiancee thought that it would be a nice idea if I made some things for decorating inside the marquee (table ornaments etc etc), anything goes. Just wondering if anybody has any ideas.
Could also be something functional - I will definitely make signs to direct people from the church to the reception locat
My equipment includes the basic tools, a router and table saw.
So – any ideas? Anything goes!
Thanks
