Woody top replacement

[38woody]

I unfortunately have to replace the top material on my 1938 woody because it tore out across the windshield. I can’t seem to find any guidance on how to replace this top. Do I start pinning it down on the front, rear, or one of the sides first? Also where is the most reputable place to get the long grain cobra top material and is the cotton looking backing you can see inside the car something that comes on the material or do I have to source that also.
