Building forts is perhaps one of the best impromptu games we all enjoyed as kids. No one really teaches you how to build a fort, but it somehow became a universal game that all children silently agreed upon.
So while make-shift forts are their unique type of fun, you can still build full-on forts for your children.
We found cardboard boxes to be an awesome tool for this particular role. Cardboard boxes are great because they’re affordable, versatile, and readily available. In addition, they come in all shapes and forms, and you can shape them whichever way you like to make the fort of your dreams.
So, to give you some inspiration, we brought together some cardboard box fort ideas.
Without further ado, let’s jump straight in.
