So my favorite flower is the carnation. I have been toying with the idea of dying white carnations with blue dye (our colors are blue and white) so that they look something like this :

For the centerpieces I was going to float two or three of them in square glass vases. I have not done any experimenting on this yet so I am not to sure how easy it will be to get just the edges dyed, though I read somewhere that blue is the easiest color to do this with.
Am I nuts for thinking this is a good idea?
