Headliner installation for a 69 coupe

[RIDETHEWALRUS]

I plan to install a new headliner in my 69 coupe this weekend. I searched through the forums and got some pretty good advice about installations for a couple of 66's and a 67. I would love some advice from those who have done this before.

One of the reccomendations was removing both the front and rear windshields. Is this neccessary in a 69 or advisable?

It was reccommended to use a blow dryer to help prevent wrinkles. If I do this should I use a little extra material so that when it cools it doesn't shrink and pull away from the bonds or is this not a concern.

I do not have an extra set of hands at this time. Is this a job that should involve 2 people (I have never done this work before)?

Is there any general or detailed advice you may have for me? It is my first time installing a headliner so any little bit helps.

Thanks
