For my daughter's princess party I built this box castle. I contacted sears and they gave me two range boxes that I cut the doors and windows out. I used the scraps to make the arch in the front. I covered it all in gray paint and drew on the brick with a black permanent marker. I then had my sister-in-law Elina, who is an artist to paint the vines and flowers on it.
All the girls came dressed as princesses and I had found a princess kit that was 50% off at Walmart. It included 4 tiaras. bracelets, earrings, scepters, and microphones. They all had a blast being princesses and playing in the castle.
