For decorations, I had saved a large screen TV box and painted it Grey and then did black mortar to make bricks...the top of the box looked like a castle wall. I wrote Princess (daughter's name) castle on it and nailed it to our swingset where the slide was...so that they came out of the entrance to the castle and down the slide. I also had flags on the castle. I also had tulle around the area for decorations and we did computerized signs for the party.
