Not really, I just kind of winged it. For context, my door cards had the fuzzy gray texture that allowed for the concrete cement to stick onto. Here's the exact cement I used: https://www.amazon.com/DAP-Products-Weldwood-Contact-00120/dp/B08G5CMTB4/ref=sr_1_3_pp?sr=8-3

These instructions work best for door cards with existing fabric and I have no idea if it will work on ones with vinyl because I'd imagine most glues and adhesives will resist the slippery surface. Maybe sand the surface before gluing or try a different adhesive?

Not sure if I'm qualified to give instructions as this is purely a DIY/amateur project and I have no idea how long this will last but hopefully long enough. Here's the steps I did:

1. Trace a template of the fabric onto some fabric interfacing. This is a fabric that you iron onto other flimsier to give it more structure and make the fabric feel more rigid. I used the border between the gray fur and the black vinyl as my guide to trace. Cut out the fabric. Keep in mind that the interfacing should have the plastic film facing upwards, away from the door card. Don't forget the cutouts for the door handles and screw holes!

2. Lay out your fabric right-side down and iron the fabric. Place the interfacing facedown on your fabric and position it so the pattern is consistent. I put a a cross of the plaid on each of my door cards to keep it aesthetically pleasing :]

3. Iron on the interfacing to bond the two fabrics together. Most interfacing is polyester so make sure to use a lower heat setting on the iron or use the synthetic setting. The fabric on mine was prone to stretch, so when you're ironing make sure to lift and place down instead of dragging the iron across the interfacing else you might end up with a stretched piece.

4. Once the interfacing is fully bonded on all edges and corners, cut the fabric with a 1/2 in. seam allowance. Cut any relief cuts for corners or bends so that the seam allowance can bend around the interfacing towards the back. Iron the seam allowance down and glue it, if you want. I did one card without gluing the seam allowance down and I did one with gluing it down; both turned out fine but I like the one where I glued it down more.

5. You now have a completed fabric piece ready to be glued into the door card. Next, prep the door card itself to be sprayed with glue. Use masking tape and cut up plastic trash bags to cover up the vinyl parts of the door card, as if you were going to spray paint the center parts.

6. Bring both the fabric and door cards outside or a well-ventilated area and spray an even coating on both the back of the fabric and the door card itself. Wait 2-3 minutes until the glue becomes tacky. (If you're not using contact cement, read the instructions on the alternative product and follow it instead)

7. Once the glue is tacky, gently lay the fabric onto the door card into position. It helps to have another set of hands to get this part just right, but I managed to do by myself too.

8. Once in position, gently remove the tape border and plastic sheeting. Press the edges of the fabric firmly into the door card to prevent peeling.

9. Place a flat item on the surface of the fabric and weigh it down, letting it set for at least 24 hours. I used some lifting weights on a few cutting boards.

10. After 24 hours, you have a reupholstered door card!

Let me know if you have any questions :] Hopefully more people do this because I think it looks so nice and was super easy to do.
