Anyone know where I can get the material for quilted door cards

Probably any upholstery specialist could do it or even your Nan if she's handy with the sewing machine!
Material of your choice, layer of foam, some sort of material for the back and some straight line stitching! And just glue it on.. To buy this sort of ready made stuff will cost crazy money! Nakamae would be one of them..

I actually found ready made door cards on carbon miata and your rite they are quite expensive €250

I have seen quilted material on eBay so check it out but my good lady made me some for less than £15. Like davith says if you know someone with a sewing machine it could be a very cheap job. If it doesn't work out it has cost you very little.
