I didn’t realize they did that until that day in ‘94, even though I’d seen other eclipses over the years. We always watched in the back yard and the crescents don’t show up on the grass. We had our cardboard and pieces of paper but we were out away from and tree shade.
I wish I had the shot from ‘94 on my HD. Different types of trees give you different crescents. The shape of the leaves makes the difference. Pine needles give you a gazillion crescents and the holly leaves didn’t show as many.
My brother and sister-in-law gave me funny looks when I laid the sheet out. I didn’t say a word until it was laid out, then just said, “Looky!” They didn’t know about the crescents until they saw them that day.
The crescents turning into circles you got to see yesterday sound really cool. I would have enjoyed seeing those.
I keep the house fairly cool during winter to save money but I still sleep with just a fairly light bedspread and sheet. And have a fan blowing across the bed. LOL The heating pad for my back keeps me almost too warm, even though it’s set on low. Just a sheet suffices during summer - - and the fan turned on high. :-)
