Most dolls have synthetic hair, such as plastic ringlets, yarn or other human-like hair. However, not every doll should have this kind of hair. Certain dolls, such as specific character dolls from TV shows, look more realistic with the use of fake fur as hair. Fake fur is not difficult to make into a doll's wig, and can be dyed any colour imaginable. If you need to make a customised colour for your wig, purchase a white-coloured fur and dye it before shaping it into the wig for best results.
Measure the doll's head where you want to glue the hair. Measure from the top of the forehead to the base of the neck, and from ear to ear. Draw a rectangle about 2 inches longer on all sides than the measurements.
Divide the rectangle into 2-inch wide vertical strips. Lay the strips over the doll's head. Pin the strips together in the desired hair pattern. You may have to pinch certain areas of the rectangles to get them to fit snugly around the doll's head.
Remove the wig from the doll's head. Sew the strips together along the pinned areas. Use a ¼-inch seam allowance.
Comb the hair with a comb to hide the seams between each section of fur. Glue the fur hair over the doll's head with craft glue. Allow the glue to dry overnight before moving the doll. Trim any unwanted fur from around the doll's face or head with scissors.
