Measurements

• 1). Measure your head or the head of the person for whom you are making the wig. Measure the circumference, front to nape, ear to ear from forehead, ear to ear from top of head, temple to temple, and nape of neck.
  
  
• 2). Record the measurement that you've taken from the head and transfer it to the mannequin head. These measurements are then marked accurately on to a mannequin head, so that the process of constructing a wig cap can start.
  
  
• 3). Before you begin sewing make sure you refit the cap that you'll make in section two to ensure that the calculations are correct.
  
  

Pre-sewing/ wig cap

• 1). Secure the cotton ribbon to the mannequin before placing a wet cotton lace over the cotton ribbon. Some people use nails and a hammer to secure the ribbon to the mannequin. Cotton lace comes in a variety of sizes you should purchase large cotton lace. Wet the lace with water.
  
  
• 2). The wet cotton lace is molded over the cotton ribbon. This mold should be secure before applying the nylon lace.
  
  
• 3). Nylon lace can be purchased in different colors, such as black and brown. The last part of making a wig cap is the nylon lace. This lace goes on top of the cotton lace and ribbon. You can sew by hand or with a machine to apply all pieces of the wig cap.
  
  
• 4). Hackle the hair before ventilating. Hackling is the same as combing the hair. A hackle is a comb with teeth that are metal.
  
  

Ventilating

• 1). Begin attaching hair to the cap. The process of attaching hair to the wig cap is called ventilating. According to Makeupfx.com, the process is similar to hooking a rug and uses a tool called a ventilating needle. The ventilating needle looks like a fine, curved crochet hook.
  
  To attach hair, take a strand or two and double it so it forms a "U" at the bottom. push through the lace cap with the venting needle, catch the strand and pull the bottom U-shaped portion through.
  
  
• 2). Knot the hair to the lace. Slide the U-shaped portion of hair down toward the needle's handle and use its hook to catch the shaft of the hair on the other side of the lace and pull it all the way through the U, being sure that it is secured around a thread of the lace. The hair is now knotted, or sewn, to the cap.
  
  
• 3). Repeat until all hair is attached. For some wigs, Makeupfx.com notes this can be almost 40,000 times.
