I used a bunch of old pant hangers from Walmart. They gave me a handful of them out of the fitting room, I broke off the clip parts (two per hanger) and used them to secure the edges of the headliner.
It’s very nice of you to help Rusty out like that Rsie. I like to see things like that on this board. Rusty is a good man and has helped a lot of us out here on FABO. Thanks for keeping this the best car forum on the net!!!
