Everything is edible. The house is made from sugar cookie, covered in fondant and dusted with pedal dust. The window is made by chopping up clear mint and placing it in the window during baking and then decorated with fondant and gel colors. The side rails are gumpaste. The girls & dog cookies covered in fondant & edible image. The tree is RKT dusted with pedal dust. I have a plate structure inside the tree that is holding up the house. I have written instructions if interested..
