hood storage bag

Listeners

I'm looking for some material to make a hood storage
bag for my 63 sprite. The material I'm looking for is a
heavy weight cotton herringbone texture material, which
is medium gray in colour.
The 62 and 63 sprites used this material for the hood 
storage bags, and I believe this same material was
used on the late 60's MGB's hood storage bags.
If anyone knows where I can find this material,
could you please E-mail me.
Thanks Greg Higgins
