I am doing a grooms cake (dallas cowboy theme) ad I want to do a 3D star. I want to do the base w/ styrofoam. Will dowel rods be supportive enough to stand the cake up?? The is my first 3D cake. Please help.

I would be worried that the tips of the star would not have any support & fall off. I do not have much experience with support systems, hope someone else can help you so I am giving you a bump.
