[NFB-Braille-Discussion] Braille Paper Weight

[Jen]

I'm in the braille proofreading course. I've discovered there are two types of braille paper. There's heavyweight (90 lb card stock) and 80 lb paper, the lighter-weight variety. Which kind of paper is best? Personally, I like the heavyweight paper because I think it holds dots better. But the NLS standards say braille books should be brailled on 80 lb paper. Thoughts?
