Build the frame first using sturdy furniture like chair backs, couch arms, or a table as anchor points, since a fort built around solid furniture holds its shape far better than one relying on blankets alone to create structure. Use clips or heavy books to hold blankets in place at their anchor points rather than just draping them, since draped fabric slides off smooth chair backs and couch arms the moment someone brushes against it. Leave at least one section loosely tucked rather than fully secured, since a quick escape route matters if the fort feels too enclosed or something goes wrong inside. Avoid building directly over or too close to floor lamps, space heaters, or exposed light bulbs, since fabric draped near a heat source is a real fire risk that is easy to overlook amid the fun of construction. Bring a flashlight or battery-powered light inside rather than a candle or phone that will die, since a dark fort quickly loses its appeal and a phone flashlight left on for hours drains the battery fast. Test the structure's stability by gently shaking or leaning on the main support points before declaring it finished, since a fort that collapses partway through play is far more disappointing than one that gets a few final adjustments up front.
