In Parshas Metzora we learn about Tzaraas (red or green spots) on a persons house. This means that the person who lives in the house should do Teshuva. Tzaraas comes to show that there spiritual problems with the people living in the house. These are mini ginger bread houses with 'tzaraas'.
Make gingerbread, roll out and using this template.
