You don’t have to get super fancy when simulating metal. Instructables user SajeewaJ makes that point with her replica of Aragorn’s coronation crown from Lord of the Rings: Return of the King. She used a form of cardboard for the build — box board. Think of the type of cardboard sometimes used for cereal boxes. Even when combined with other supplies such as glue, cord, and paint, the build is quite inexpensive.
She started by drafting the pattern for the various parts of the crown and then traced them onto box board. The make the edges of the crown look embossed, she used applied cord to the top of the cardboard with glue (see the below picture). She says:
To make the edges embossed, stick the white color cord as shown in the figures.
For the largest two, stick two separate lines of cords.
Paint the cord in silver color and then paint the board parts in bronze-golden color. (mix the bronze and yellow colors)
