I've been doing this for years with grand kids,take two full length graham crackers, with serrated knife carefully cut corners off one short edge of each to form a pointed top. Take two half crackers and glue(royal icing) to tall pointed crackers ( the bottom half leaving the pointed half clear for roof)take two halves and glue to the top edges for roof. Let dry and decorate. We have a blast with these every year. So easy,simple and quick not to mention cheap. Sometimes we make them for valentines and Easter. Hope this is what you wanted.
