Carefully cut out rectangle shapes from a piece of cardboard.
Cut one short end into a point to make a roof shape.
Using the white paint marker, outline the house in white paint.
Using that same paint marker, draw on a door, roof, windows, and little bits of detail like hearts, dots, and trees.
Carefully trace over the white paint with a bottle of craft glue.
Over the trash can, pour white glitter on top of the cardboard gingerbread house and carefully shake off the excess into the can or over a piece of paper.
Let the gingerbread houses dry.
Now you can add a loop of string to the back for ornaments, stick a magnet on the back for the fridge, or just decorate the house with them.
