There's a pretty talented artist on Facebook whose work I follow and after seeing some of the results she achieved, I asked what she used to mask off the area, and she replied with this picture.
Unfortunately, there's a bit of a language barrier, and it's kind of hit or miss on whether we understand one another, so I figured someone here may know?
The item in question is shown in the pic below. It's some sort of fine mesh. I've tried tulle with very poor success, so I don't think that's what it is.
Any ideas?
