Unique Wedding Ideas

I am pulling together a wedding renewal for my sister on an extremely tight budget. I want to know if anyone has an idea of how to save money on centerpieces and alter arrangements. The Hershey kiss roses are such a great idea for favors. I made them for a friends wedding and attached cards with satin ribbon on each bride and grooms name, date and a brief thanks !! My children handed them personally to each guest and it was beautiful! I figured I would share as well!
