Parenting books frequently suggest building blanket forts as an activity for parents to participate in with their children. A blanket fort is made by grabbing blankets around the house and setting them up in a room-like manner.
In popular culture
According to Guinness World Records, the largest blanket fort ever was 1141.79 m2 and was built by Cub Scouts Pack 502, Scouts BSA Troop 502B, and Scouts BSA Troop 502G from Mount Pleasant, South Carolina. The record was attempted "to empower the scouts towards meaningful service and to engage, raise awareness, and respond to needs within their community."
