While surfing around I came across this great tutorial on making these lovely centerpieces by Lindsay Wierzbinski, and I thought I would share them. These were made with white Carnations, but you could use any flower, fresh or artificial. I just love this idea.
Another idea is to use cupcake liners. These are adorable and the instructions for making them can be found on Kara's Party Ideas.
You could even use Coffee Filter Roses that you can make yourself.
