Ahhhhh, HELP! I am seaching high and low to find just TWO 32x40 foam boards that are super sturdy for 2 large cupcake cakes but have yet to find any that are not sold in bulk!!! Does anyone know where I can get them, need them ASAP?  If it comes to the point that I need to go with plan B is there another option as far as boards go? I see a lot of people  like to use plywood as well but how does that work?
