I combined 3 circle shaped styrofoams together to make the head of the key staff. For the patterns surrounding the rings, i used cardboard. For the handle of the staff, i used 2 wood poles. I make it in such a way that it is detachable for easy carrying and cause the staff is really long ~_~ For the bottom part of the staff, i make use of styrofoam and cut the pattern out. Lastly, to make the whole prop sturdy, i wrapped many layers of gum tape around the prop.
