Seconded for asking the specific threads, theres a lot of experienced people who maybe only check certain threads
As for the hair,keeping it as light as possible will be key, and of course with Twintelle's hair being ridiculously large (and fabulous!), you may want to keep transportation etc in mind when you decide how big you want to go.
I would personally go with a light wire structure with the hair covering, and would make the black on the face as a mask rather than make up. This could be attached to the base of the wig to make it that extra secure.
