Summarize the following:
Cut the thread or embroidery floss to your desired length. A good rule to follow is measuring the thread against the chosen strand of hair and make the thread 2-3 times longer than your hair or the extension you are wrapping. Measure out as many colors as you want to add to the first wrap and lay them out together. Once you try these basic designs, you can try new ways to create different unique patterns on your own braids. Most commonly, people choose to wrap just one braid but don't be afraid to wrap several braid strands or even do your whole head! You can keep your hair wrap in for a couple days or an entire month.  Most people decide it is time to remove the wrap when it starts to smell or feel funny. No matter what, do not leave it on longer than a month. An old wrap can mold. If you want to keep rocking the wrap look, remove the old one and start a new one on a different piece of hair. To remove the hair wrap, carefully snip the knot off and unravel the thread. Be careful to avoid cutting your own hair.

Summary:
Measure out the length of thread. Have fun creating your hair wrap - be patient and be creative!
