Anyone who knows how to sew can do it.  There's a threading tool that
you milk through the channel.  Use strong elastic - my wife did ours
and it was only about half as strong as it wanted to be.  It's got a
lot of weight to support and heavy fabric to bunch up.  Even weak,
though, it worked tolerably once the visors were folded over under
it.  I don't have one here to look at, but I might be inclined to
consider using thin marine shock cord if it will fit.  Might have to
use a different kind of fishing wire for that.  Sorry I'm being
vague, I've never looked at the details of them (or have forgotten).

Yours,
