Useable width of Ed's 67" Sil?

I'm about to begin making a BlackCat tarp, but I only have half the sil I need. I ordered the other half from Ed at Speer Hammocks, but I want to get started with the material I have in the meantime. So...

Is the dark gray 67" sil exactly 67" wide **including** the unusable frayed factory edges? If so I'll have to cut it down an inch or so on each side to eliminate the edge, so I need to take that into account now.

Anyone who has ordered this Sil from Ed, let me know! Thanks.
