I have to start ordering our centerpieces and would like suggestions or help...I am DIYing everything and love the look of the centerpieces being tall cylinders with submerged flowers. Now the question is should I go with 3 different size cylinders, 2 different, or 1 big one? If I go with 2 or 3 what sizes are the norm? I see pictures but it doesn't state what sizes they have used so I am stumped and a visual person so it's very hard to make a decision!
