Mad scientists have white eyebrows that stick up wildly, cavemen have bushy unibrows and Santa Claus has bushy white eyebrows that are neatly combed. Fake eyebrows can enhance many costumes. They are available at costume supply stores, but they are expensive and the selection is limited. Make-up can be used to draw in small, neat eyebrows, but for large, extravagant eyebrows, fake fur is the best option; you can use it to quickly and inexpensively make any style of eyebrow your imagination can devise.
Measure the width and height of your eyebrows and draw a rectangle the same width and height on a piece of paper.
Draw the shape of eyebrow you desire over the rectangle. Be sure the new eyebrow is at least as wide and thick as your current eyebrow so it will cover it completely. You may draw one or both eyebrows. Cut out two copies of one eyebrow to make a pattern. This will ensure the eyebrows are symmetrical.
Place the pattern pieces on the back side of a piece of fake fur so that the fur is pointing up and to the outside of the eyebrow, the way eyebrow hair grows. If you want particularly wild eyebrows, place the pattern so that the fur will be pointing straight up. Be sure to turn one of the pattern pieces over so that the eyebrows will be mirror images of each other.
Trace the eyebrow patterns on the back of the fake fur.
Cut out the eyebrows along the lines you drew. Try to cut only the fabric backing and not the fur.
Brush the fur on the eyebrow into the style you desire. You may use a tiny bit of hair gel to hold the hair in place.
Trim the hair of the eyebrows as desired.
Use spirit gum or toupee tape to hold the eyebrows in place.
Grease paint can keep the brows from sticking. If the brows will not stick, clean the area where they will be placed with make-up remover before applying the gum or tape.
