My house was in the path of totality, but there was about 90% cloud cover, giving me problems while watching the eclipse. Since my wife was attending a band concert/eclipse party about 45 miles to the SE (she has personal friends in the band, but I stayed home with the pets), when noon approached, I reached for the box that the shade #14 solar glasses were in (we ordered two pairs), and found that she took the box without leaving me my pair. Fortunately, a couple of weeks prior, I cleaned and tested my auto-darkening welding helmet (shades #8-13), that I'd used in an earlier partial eclipse years before. So, I used my helmet on April 8.
Problem: the 90% cloud cover (and the expansive Oak tree-leafed canopy covering my whole property) sometimes made the auto-darkened helmet switch off, allowing full sun. I played around with it, and found a way to have my eyes focused just below the eyeplate, so I'd be able to see when the helmet was fully darkened. And, for the height of the event, the cloud cover got a bit thinner, and I was able to observe without going blind.
The super dark shade #14 glasses are the ones recommended by most authorities, though they are too dark for much else. My helmet would darken to shade #13, which will protect eyes from the sun, but not as well for long periods. Any shade lower isn't recommended, per what I've read. But, I'll not advise using an auto-darkening helmet if there are clouds making the helmet have inconsistent protection! Maybe, before the next one over the continental US, excluding Alaska, in 2045 (I think), I'll get a better full-time darkened helmet, first. But, as I'll be 95 then. knock on wood, it's not of great concern to me.
Here's the photos I took (in between tripping over things in the darkened yard):
