I managed to get some white (Ivory) coloured faux leather from ebay (https://www.ebay.co.uk/itm/FAUX-LEATHER ... A6q1KedpcQ) They sent me a sample within 2 days of requesting a piece and it was a near enough match for my cars ivory interior, although had a sheen to it. I ordered 1/2 metre for just £6.50. In fact there is enough to undertake 4 'A' pillars so lots over if you make a mistake!
The 'A' pillars actually detach quiet easily using either 'brute force' or with a plastic spatula. Don't forget to unclip the sensor wire inside on both sides of the 'A' pillars. They do come out easily. The nearside with the speaker looking cover has a single screw holding it in place. Remove screw before attempting to wriggle the fitting out of the 'A' pillar. It has to be twiddled a bit but it will come out, just be careful. Once off, one can remove the nylon trim by pulling off the material then cleaning up the remaining glue using something like Evostik Adhesive remover. Once the plastic is cleaned up they should look like this:
Then it's a case of using the old nylon material as a temp plate to use to cut out the faux leather.
