Boil molasses. Add margarine, milk and sugar. Sift dry ingredients together into a bowl. Add molasses mixture and mix thoroughly to create dough. Roll dough out between two plastic sheets to the thickness of a coin. Transfer rolled dough to parchment. Cut out house parts. For stained glass, break clear colored hard candy into 1/4 inch pebbles and drop a pebble into each window. Bake six minutes at 325 degrees. Allow to cool completely before removing from parchment.
