Summarize the following:
Some people like to create 1 to 2 French braids, while other people prefer cornrows. How you braid your hair now is very important, because it will affect the size and shape of the wig cap.  You need to take a mold of your head in order to modify the wig head. If you don’t do this, the cap for your wig will not fit you.  If you already own a canvas head for wig making that has the same measurements as your head, you can skip this part and click here to continue. Be sure to extend the plastic wrap past your hairline. This includes your ears, forehead, and nape. Extending the plastic wrap past your hairline will reduce the chances of the tape sticking to your hair in the later steps.  Use clear plastic wrap, if you can. It will make the later steps easier. If you have a nylon wig cap to wear under your wig, it would be a good idea to put it on first. If the plastic wrap is slipping around too much, secure it to your forehead with a piece of scotch tape. Wrap the tape around your hairline first, taking care to avoid the skin. Cover the rest of the plastic wrap in overlapping rows of tape. Do this step twice. There should be no soft spots left. If you feel a soft spot, that means you missed the plastic wrap. Cover it with a piece of tape!  The taped plastic will have some give to it, which is fine. It should not be soft, like fabric. You need to use clear packaging tape, otherwise you won’t be able to see your hairline in the next step. It would be a good idea to get someone to help you with this, especially when you reach the back. If you were to look at yourself in the mirror, you should be able to see your hairline through the taped plastic wrap. Trace all around your hairline, from forehead to nape. Be sure to include your ears as well.  Don’t worry about getting the marker on your skin or hair. This is why you extended the plastic wrap past your hairline! If you don't have a helper, turn your back to a mirror, and hold a smaller mirror up in front of you so that you can see the back of your head. You should be able to simply slide it off of your head. If you can’t, dip your finger in water, then run it along the inside edge of the cap to separate it from your skin.  If you still can’t get the plastic off, carefully cut a slit into it (preferably the back), then slide it off. If you put a nylon wig cap earlier, it may come off with the plastic wrap mold. Simply peel it away. Follow the line that you drew with a marker, leaving a 1⁄2 to 1 in (1.3 to 2.5 cm) border. Make sure that you cut out the ears as well. When you are done, you should have a cap that fits perfectly on your head, and follows your hairline and ears. If you cut a slit into the mold, you will need to close it up and tape it first. Next, cut off smaller pieces of tape, and use them to cover the inside of the mold, overlapping them as you go. If you want a nicer finish, you can wrap tape around the cut edges of the cap.
Pull your hair back in the same way you’ll be wearing it under the wig. Cover your hair with plastic wrap. Cover the plastic wrap with 2 layers of clear packaging tape. Trace your hairline and ears with a permanent marker. Remove the tape-covered plastic wrap. Use a pair of scissors to cut off the excess tape and plastic wrap. Reinforce the inside of the plastic mold with more tape.
