Bows must be in the correct original order
Put the headliner in the sun to make it more plyable
Start with using the middle bows and start stretching out from there
Glue the edges of the headliner and trim as needed
get the edges under the rubber glass gaskets and hook it into those sharp teeth
use a razor to cut slits for the dome light, coat hooks and visors, some put the screws in and leave them so you can find them under the heaqdliner to make the cuts
Heat gun out the wrinkles
