Once I got the shape that I wanted, I took strips of plaster and covered it. You want to be careful not to use too much, because you don't want to make it too heavy, it will be resting on the top of the head. I just wanted it wrapped up so it could cover the tape. You really don't need to worry about sanding it or anything, since it'll be covered.

When you're fitting the base of the wig to the head, you want to make sure you have a way of securing it. I ended up hot gluing it to the top of the wig, so it would hold there while I could work the hair along the base. This is a bit more complicated to explain, but I'll through the process I went to attach the hair to the base.
First thing I did was take a clump of hair and spray it down with hair spray to make it stiff. Then taking the spray mount, I would spray it onto the base and then press the hair to it. Taking a brush, I would paint the mod podge along the hair to help make it more stiff, as well as stick it to base better. I would repeat this process until the base was completely covered in hair. In the end it looked something like this...

Not...incredibly nice. But it will look better! This is where the second wig came into play. I harvested the second wig for wefts and attached the wefts in the same way I attached the hair from the wig.
I didn't really do much differently from the last part. The ends of the hair was painted with mod podge to make them stiff, so I could create a hairline for the wig.

Slowly but surely the wig was starting to look more even, less like a mess of hair around the base.

And the final result was this!

This was probably the biggest wig project ever. It was tough...but I was glad for the experience.
