Is it Nylon or Dacron? Anyway, I just tie knots in mine.

Why not just use the same system used on tents that use rain fly covers?
Not sure how to describe it but you can find them on almost any light weight
tent.
Just use a bigger version.
Most use light aluminum but heavy Plexiglas or Lexan would work just fine..
Here's a fancy version

I've seen ones that are basically steel wire bent into an appropriate
shape, and, of course, the 3 hole toggle kind: like these
http://www.campmor.com/line-tighteners-2.shtml 8 for $2

The steel wire ones are basically a ring on one end, and a sort of
dual slot thing, hard to describe in words. Functionally identical to
the campmor ones.

And, there's another scheme with two overlapped rings, like you use
for tightening a strap or buckle.
