How to put it together

1
Print an octagonal bipyramid (3D diamond) papercraft template onto your green cardstock.
2
Carefully cut out the template along the solid lines and score along the dotted fold lines.
3
Fold the paper along the scored lines and use hot glue or double-sided tape on the tabs to assemble the diamond shape, leaving the bottom point slightly open.
4
Insert one end of your sturdy craft wire into the bottom opening of the Plumbob, securing it inside with a generous amount of hot glue, then seal the paper shape completely.
5
Wrap the other end of the wire tightly around the center of the headband several times, securing it with hot glue so it stands straight up.
6
Put on your casual outfit, place the headband on your head, and gently bend the wire so the Plumbob floats directly over the center of your head.

Makeup & hair

Style your hair in a neat, simple fashion. Keep makeup clean and natural, mimicking the bright, slightly stylized look of a default video game character.

The Sims for couples, groups, kids & more

couples: One person wears a green Plumbob (happy mood), while the partner wears a red Plumbob (angry/low motive mood).
group: A group of friends wear different colored Plumbobs (green, yellow, orange, red) to represent a full household of varying mood levels.

Tips

Use lightweight cardstock rather than heavy cardboard so the Plumbob doesn't wobble or weigh down the headband.
If you are wearing this to a nighttime party, place a small, lightweight green LED finger light inside the paper shape before sealing it to make it glow.
Wrap the base of the wire on the headband with black electrical tape to prevent it from scratching your scalp.
