Yeah, it looks great and, on the original Advents, the cloth on the walnut version was different from the utility version. It is softer and fuzzier. The cloth on the utility version is stiffer and the threads are more "cohesive" so the openings between them seem more "open" as you found.
I am ordering a couple of the 18" X 27" size for my very early walnut pair, the cloth of which had yellowed terribly long before I bought them. I tried to restore it but to no avail.
And finally, some 18 count fabric of the correct color. I have always been able to find the correct color but not 18 count or, the other way around.
