April 2016: Like many early C4's, my car had a problem with the carpet pulling away from the door panels. This usually appears as a 'scalloping' effect where the carpet droops in the areas where the factory glue is failing. Because I'm not ready to shell out the cash to buy new door panels yet, I decide to find a good but cheap way to fix this.

I went to eBay and purchased some black upholstery thread (Black Bonded Nylon sewing Thread #92 T90 for Upholstery) and some blunt tapestry needles.
