I use a couple websites since I don't have any Detroit books/do too little work to buy them all

https://oemautofabric.com/detroit-books/

http://autooriginals.com/

https://www.miamicorp.com/default.aspx?file=customer%2fmicorp2%2fcustomerpages%2foriginal.htm&Page=customer

sometimes its heard to tell on a screen, but usually can narrow it down, or buy a half yard of each one you think.

Thanks I’ll save these sites. Yeah I don’t do enough to justify Detroit books either. But now the customer just wants close and by that they mean anything cloth that’s any shade of grey....wish they told me that from the start lol

I think Albright's also has Detroit books on line.
