I need a base big and tall for this bouquet. The styrofoam shapes at walmart and michaels are not as tall even with a round base underneath. Is there a website that sells big or ttall styrofoam bases. I also need one big for a tall strawberry tree.

Are you looking for a cone shape? (Your post isn't very clear, sorry.)

I know this site has lots of styrofoam dummies for cakes, maybe they have what you're searching for?
