Snow fort windows are too often crude affairs, primitive peepholes bored through the walls with a stick and then widened through the age-old wiggling technique. Here we present a far more durable--and aesthetically pleasing--approach. Using the adjoining walls for support, we laid a sturdy board across what would become the top of the door or window, then continued our rows of snow bricks to cover it and complete the wall. As for the bandanna curtain, it's either decorative or defensive, depending on who you ask. Hung on a stick secured on either side of the snow-framed window, it serves those who prefer to host tea parties as well as those who need to keep an eye out for invaders. Other colorful bandannas, tied to sticks and set as flags on the fort's ramparts, complete the decorating theme.
