spackling cream

i don’t even mean to be baking, but i need a base to pipe. I tried making fake cakes, selling them as art, there’s less burn scars and ingredients that can spoil. my biggest fear is making someone sick, so trust it’s clean and a little compulsive. i made a fake cake with spackling as the buttercream, the same thing used for drywalls, and covered it around styrofoam. the fumes were unexpected. i’m dizzy, but it’s worth it. my lungs disagree, but the rent doesn’t include ventilation.
