This was the 3rd time I've done it. I had black and red plaid in my 93 s10 about 4 years ago and a few years ago I did my wife's car with some pink and purple plaid. Wish I still had pics of them.
I just found something I liked. Took all the plastic trim down being sure not to break any of it. Had to remove the visors, rear view mirror, oh s*** handle, ect. CLEANED the s*** out of the headliner with some degreaser then soapy water. Got some 3M spray adhesive. I layed the fabric on the headliner and squared it up so it was semi straight. Folded about 6" of the fabric over and sprayed the fabric and the headliner. Folded the fabric back over and pressed it down onto the headliner. Then folded the rest of the unglued fabric back over what was already glued. Sprayed the fabric and headliner in 6" sections and slowly worked my way to the end. I should have made a 'how to' with pics. Would have been easier to explain lol
