100% linen sheeting fabric

My wife and I want to make our own 100% linen bedding.  Unfortunately, we've failed to locate fabric for this (i.e. 100% linen fabric in a sheeting width of, at least, 90").  We've queried several of the major fabric retailers about getting it through special order, but they're unable to provide it.  This fabric does exist, of course, because linen bedding exists.  Does anybody out there know where we may find it?  Thanks.

I've purchased linen online from fabrics-store.com. I haven't looked specifically for the width you require but they have a decent website, very reasonable prices and will send free swatches so you can really see and feel the linen before making a purchase.
