Things You'll Need
Instructions
Choose a location for your forts. If you are playing outdoors, select a location with architecture that you can incorporate into your fort, such as trees or lawn furniture. If playing indoors, select a location with enough room to construct the forts. Remove any fragile objects from the fort area.
Build the underlying architecture for your forts. Use furniture, clotheslines, tree branches and other large objects to create your forts' frames. Arrange the objects in the layout of your choosing.
Construct the walls of your forts on top of the frames. Use bed sheets, blankets, couch cushions, pillows and other easily malleable objects to create the walls. If you are playing with projectiles, such as plastic dart guns or dodge balls, use cardboard, tarps or chipboard to give your forts added strength.
Add details to personalize your forts. Leave flaps closed for hidden doorways or leave small gaps in the walls for spies. Tie pillowcases to cardboard tubes or broom handles to create flags that you can fly above your forts.
Decide on the rules of your game. Try hiding small flags in each fort and playing capture the flag, or lay siege to a fort with water guns and toy balls. If you have enough players, each player can have a different role. One could be in charge of keeping watch, another could run spy missions, others could play infantry roles, and so on.
