I found some 60" tulle at JoAnn's and bought 7 yards of it and asked them to cut it into two 3.5 yard lengths.
I then sewed it into a "tube" with cord channels on each end which I threaded 1.75mm nylon cord in each end with cord barrel locks on each end allowing the fabric to be gathered tight.
The foot end used a much shorter cord so it doesn't open up nearly as much as the head end that opens all the way.
It is installed over the hammock's ridgeline so it can slide open and closed easily. Every 1.5 feet, I sewed short grosgrain loops along one seam so it can be threaded onto the ridgeline; also preventing it from rotating.
On the same seam, above/near my knees, I sewed in a custom-made small mesh stuff sack for the bugnet to stuff itself into, but usable for lightweight gear storage when inside the bugnet.
At barely under 10.5-feet long and 120-inch circumference, I know that the bugnet is probably much larger than it needs to be. However, the whole setup only weighs 106g/3.74oz so I am not to bothered by it's size. Plus, it stuffs pretty small anyway.
