This video by Ustrology provides instructions on how to build a Gingerbread House with LED LIGHTS and Sugar Windows.
https://youtu.be/FTp5YYAZcB4We built two ginger bread structures, a house and the Cybrid bus which operates for Iowa State University. The snow is a combination of flour, coconut, and most importantly sugar which really made the snow look real. The windows were made from melted hard candies. Of course we need also to make a pretzel balcony with oak (chocolate bar) doors. We had a lot of fun, enjoy our work and MERRY CHRISTMAS!!!
