Found this at Ikea for $5..

$5 for 2 == 110"x98".. should be big enough for 2 hammock bugnets. it looks similar to tulle, only much stronger. It won't stop no-see-ums, but it will stop mossies... It's white, but I've had a lot of success with spray dyes, which are also cheap. Even spraypaint works, but is heavier.

Packaging says 14oz, so that's 7oz per, at 110x98 ... um...

7oz/110x98=10780 sq in / 144=74.86 sq ft /9=8.3 sq yds = ~0.8oz/yd^2

Not bad for $5.
