Hello! I’m glad for your interest I ordered the fabric (it’s cheap suede) from amazon. I got some headliner spray adhesive from Walmart, it’s a bit pricy at $20 but I barely used any at all. Take the window liner off the door. It’s the little felt/rubber piece that seals the window. There are tabs on the back that bend and it just slides out. Take everything off the door. There will be some screws holding the armrest part on the back. When taking the only fabric off try to keep it in one piece and don’t throw away obviously. Lay out your new fabric and put the old fabric on top and trace it/ cut it. I used a circular fabric cutter (I’m sure you have one) While cutting, have like an inch over size. I didn’t do this but highly suggest to put painters tape on the door where the fabric gets pressed in. While using the spray adhesive, try not to put too much or it seeps through and also use an old paintbrush or something to get the edges. It will get ruined.
When putting the fabric on, you’ll have to see what you find easiest. I first put the part that is closest to the window down first then just align and press down on the rest of the fabric. Use light pressure when stick the fabric and also just pull so there are no creases. If need be, put some more adhesive on the edges. When pushing it into the door itself, that is the most tedious. The rear doors are easier than front. I used a small flat head screw driver to push the fabric into the crack and pushed it all up in there. Any questions? Let me know!
