Anyone have any good tips on items to use and what to use to adhere them to the inside of a mask?
I used to take the black screening from cheap Halloween masks and used tacky glue to apply it to the Myers mask inside.
Black sheer nylons & super glue.
Worked like a charm on my RRv2.
They easy to see out of>?
Well there is a screen covering the eyes, so there is limited visibility there, But overall, not bad at all.
Yeah obviously going to be somewhat limited 
. Most masks ive seen use regular door screens as well… unfortunately dont have any of that.
Super glue works like a charm, just dont use too much or it will rest on your face as super glue stiffens like a rock when it dries. I use super glue to screen a mask and used too much and left areas were it rested on my face and it wasnt pleasent, Had to cut some of it out with a knife.
I was told they used plain duct tape to keep the mesh in place for some of the masks
lol! No way!
I guess it could work… would be less permanent too
