Abstract
A collapsible playhouse made from two halves of sheet material, such as corrugated cardboard, secured together. Material is applied at the edges to make them smooth and prevent cuts from being inflicted on the user. The applied material also strengthens the edge areas. It may be provided in the form of tape, or of tabs extended from the free edges to be folded back therefrom. The edges could be compressed to the normal sheet thickness by running the material through a roller press.
