If you're throwing a gingerbread house decorating party, you'll obviously need gingerbread. Decide how you want to tackle this. Are you ever the DIYer who can't buy something when it can be homemade? Or are you the type to accept that sometimes, life is easier with something store-bought? If you're the DIY type, get started well in advance by baking your gingerbread house sections. But for a bit of ease, head to a craft store and pick up a few pre-made and assemble gingerbread houses.
