Using one side of a pair of binoculars held over a shoulder to project the sun onto a white surface set up to be perpendicular to the sunlight and in your shadow works better yet.
That’s a nifty idea. Hubby had a couple pairs of binoculars and now that I think about it, I have a monocular that was Dad’s. That will be easier to use.
Still going to lay out a sheet under the Bradford pear tree for a pic or two of the shadow crescents. Pretty cool to see clusters of them in the leaf shadows.
