Playhouse Safety Rails

I had just enough time this morning to install temporary safety "railings" on the windows around the loft.  Renee also helped me do it.  I want to put the railings up now so that Russ, Renee, and their friends can safely play in the playhouse next week, while I take a break from construction.  It will be gratifying to see the kids enjoy the playhouse when I get it to a usable state even though it still needs, windows, doors, a roof, siding, etc.
