That's a really cool tutorial you posted, LKD! For this particular wig I would try a similar technique but with quilter's batting (instead of rollers), since it's so light and you can paint it. Also, buy extension wefts! You'll want to attach them to the inside of the wig and pull them over so that netting doesn't show along the edges.
