not here yet, but...
The surplus nets I have been around, although it's been a few years ago (maybe 25 yr) were nowhere near stiff or heavy. Regardless, I'm not concerned about an extra pound in netting as long as the kids aren't the main course for a mosquito buffet. I have my fingers crossed that it's reasonable stuff to work with & I'm into savaging materials when I can. If it's good stuff, $7 for a 200x68" chunk ain't too bad.
