Do you use welding lenses to view the event, and if so, would you know the best shade number to use? I've also seen folks using a piece of paper with a small hole in it to view the sun...don't know about trying that paper trick myself tho.

That's something that I have been researching too, but I did come across this information posted by NASA at (https://eclipse2017.nasa.gov/safety ) and its pretty helpful. From what I gather it is best to use something that is compliant with the ISO 12312-2 safety standard.
