Lining a fursuit head - there has to be an easier way?

I feel like I'm really making it way too hard for myself when I line a head and would like to line my heads more efficiently and just better in general. It is frustrating and I keep trying different techniques and every time it takes me forever.

Right now I'm using lycra and I usually "attempt" to make a tape pattern of the inside of the foam head and sew the lycra, which never ends up being the correct size so I have to stretch it into the head while gluing it and urrrggghhh....so tedious and frustrating. The last time I lined a head I ended up just tearing the back of the head open to line it and it still was a pain in the rear.

So how is the best way to pattern the inside of the head and the best material (it seems like the glue soaks through the lycra that I use in some areas sometimes....is that a common thing?) and what do you guys do in general to work quickly and efficiently at this process. If you guys have pictures of how you do it that would be amaaaaazing because I suck at understanding things.

Thanks!
