Tulle and poly pipe placed over central broccoli

Got my 100 ft of poly pipe today (3/4 inches X 100 ft. 75PSI white stripe, from Home Depot), so rigged up some poly supports and placed the new white tulle (from the store that shall not be named) over it.  The poly pipe arches are supported by bamboo stakes sawed down to about 18-20", and also by some random long plastic stakes I had.  (Worth a try to save the cost of rebar stakes, especially since the only pre-cut rebar stakes I could find are $4 each -- that would add up.)

The tulle is definitely much nicer than the FRC -- can really see into it well!  The only thing is it wasn't quite long enough to cover the entire central broccoli, so the two northmost broccoli are now without cover.  The tulle size is 54" by 108" and cost $12-$13, so not cheap especially if it will last only a season or two.  Would like to find where to buy a big bolt of it for better cost.
