How to create a basic gingerbread house:
Step 1: Pick your design
Step 2: Cut your house including the walls and roof into cardboard pieces
Step 3: Make your gingerbread cookie dough. Then lay the dough on top of the cardboard pieces and cut into the proper sizes. Depending on your design, it may be easier to lay a piece of foil over the cardboard then place the dough on top to cut. Then you can grab the foil and slide the cutout on to the cookie sheet rather than picking up the soft dough and moving the piece. Also, it suggested to label the foil to ensure that you remember which piece is which.
Step 4: Let the dough sit to harden then start doing the detail work on each piece individually. Make sure to let the decorated gingerbread harden before you start building.
Step 5: When you are done with all the detail designs, start to piece your house together with glue or frosting on some sort of base (cookie sheet, pizza pan, wooden board, ect.). Depending on your design, you can use the cardboard behind the design to keep it sturdy then attached the gingerbread to the cardboard.
Step 6: Once the house is built, begin to add other details, frosting or start designing the base it's sitting on.
Step 7: Enjoy!
