I made a food net for Christmas, although to be honest I use the first one I made all year! My old one has lasted a few years and regularly goes through the washing machine - although I wouldn't recommend it as its made the silver bells go dull.
I'm still working through my stash; this is fine net with glitter, I edged it with a thin white lace and sewed on some green leaves and silver bells. its about 1m x .75m. I like them BIG - then you only need 1.
The bells and leaves work well to weigh the net down on the edges.
