and here's the steps up to turning the neck which does get messy using this method
but neat enough when the wig is put on and the loose fabric flaps are sewn neatly.
I put on a layer of tacky glue and spread it with a brush... a GOOD one... so it will NOT leave hairs. Then, determining the bias of the fabric going up and down on the exact middle of the face like a diamond square of fabric, I start pressing it in with a combination of tools and clean finger... you'll note that parts of the fabric are not adhered in some of the photos -yet-. Manipulation and the tendency of silk to suck up tight as it dries mainly takes care of this problem. And, I'll admit, lots of practice with some fails!
You will note the silk has already tightened in the short time it took for these photos to be taken... I have no doubt now the neck is turned she will turn out fine!
