In the photo below, I have finished making his wig cap, adding about 2-3 layers of glue.
I then trimmed the wig and creating a hairline. I just used a pencil to sketch out were I wanted the hairline to be.
Here's the wig after it has been trimmed.
For the hair, I just used yarn. By combing out the yarn, the fiber are less together? I really don't know how to describe the yarn becoming more hair like, BUT THE PICTURES WILL SHOW YOU! Also, you will end up losing a lot of fiber, the more the merrier if you want a fuller and thicker looking wig. And disclaimer, I cannot take credit for this idea, since I came across it on Google while searching for a wig making tutorial. However, I can say that you'll find more details on the matter by searching for "brushed yarn wig."
