I am currently trying to find out what to search for online to be able to look up pricing on this particular kind of fabric. Also if you have a better idea, please feel free to mention it. I am trying to create the look of folliage above people's heads in our theatre by using something that is similar to fish netting and lighting it with green lights. While I have found fish nets, I remember seeing at DisneyWorld a sort of fabric that was a sheet with partial holes cut out in order for the fabric to have some dimension. They then lit it with green light and it really did look like green folliage. I think I may have seen this sort of fabric used by the military perhaps. Does anyone know what I am talking about? Also if you have any idea on doing a folliage above peoples heads sort of look for a reasonable-ish cost I'd appreciate it. I am thinking of buying a bale of fake spanish moss and use it with fish nets to give the idea of trees. I would love to buy enough enough fake limbs or leaves to do it, but would be probably too expensive. Thanks for any ideas or help on this.

I assume you mean by 'above peoples heads', this is on the stage?

We have done something similar with erosion nettings - word of caution - whatever you use, make sure it's fireproofed in case the fire marshal drops in on you.  Just spraying on some watered-down fire retartant will save you from a work of hurt.
