No doubt, for nylon purists, an essential element of the pantyhose encasement process involves covering the head. For those of you who do this, what is your comfort zone regarding layers of nylon encasing the head?

Also, do you even like to add other materials with the nylon too?
For instance, I've often encased my entire head in bandages prior to adding two or three layers of nylon over the top! The effect looks eerie and strangely erotic at the same time ... but it feels so good!
