I have worked in the textile industry for the last fifty years, have used thousands of yards of Ultrasuede and many of the other synthetic suedes on the market and have been getting a very nice synthetic suede for many members of the Jaguar forums for Alcantara headliner and 'A' pillar replacements for the last few years. If you go the Ultrasuede route (this is a brand name for a continuous filament synthetic suede), I would just caution that it has a tendency to "pill" when rubbed enough times (as in when you would wipe or vacuum it down). It is also very expensive from about $80-120/running yard at 54" width for the upholstery grade (as there is lighter weight apparel grade as well). The suede I have been getting for members of the Jaguar forum is called Passion Suede. it is a woven fabric, so it is strong. It has a very nice nap (very suedelike look), comes in over a 100 colors, and runs under $5.00/running yard at 60" width. It is a wonderful microfibre suede of which I have personally used thousands of yards for clients for couches and chair upholstery over the years. I usually have some pieces laying around, leftover from a project or job, so if you'd like a sample just let me know, and I'll send it to you. I am assuming you want black but maybe not. I just finished using it to reline the front trunk on my Pantera, and will next be recovering the rear tub in the same. Without a single negative comment, every Jaguar Forum member to whom I've ever sent it has been surprised at the quality and price. Let me know if I can help. When last I bought it a couple of months ago, my source charge $4.95/yd.
