Headliner help?

In addition to the contact cement ( in moderation, the glue can squeeze out of the design perforated holes and make a mess) , I used at least twice the amount of clips than the factory used, like one on each side of the bows and one in the center of each section.

yes i also used twice the amount of factory clips after the contact cement dried. but while i was installing the headliner i used a whole bunch of those office spring paper clip things till the cement dried
