To make a Dalek costume, first get an idea of the shape and costume you want to make. Build a frame for the Dalek's base. Use lightweight material to construct a circular frame. Attach sheets of cardboard to the frame using string tape to cover the frame. Create a frame for the Dalek that will cover your torso. Measure your shoulders to find the width for you to fit. Build the head. You could modify an object such as a large bowl. Cut foam balls in half and glue them to the base using hot glue. Spray paint all parts of the Dalek costume, and let it dry before wearing it.
