Yes, I read that too, and thought anyone who says that clearly has trouble deciding if the milk or the cornflakes go in the bowl first.

I am curious where this guy is getting his supply though.
I have looked at a few overseas sites and haven't found just what I was looking for; but I pulled out all the stops and tried a search for 'alte lautsprecherstoff' today, and found this lady:

who has a number of speaker cloth patterns, and claims that if you send her a sample, she will do her best to reproduce it, even apparently to the extent that she will send you approval samples when in doubt about color or thread type.
She looks a bit expensive, and I'd prefer American parts throughout, but any port in a storm I guess.
