I'll admit: I'm largely guilty of this. Which is why I am so pleased to show you this:
I saw a similar idea on Pinterest using traced handprints cut out of paper and stacked and wanted to do it on stretched canvas with paint. And then I actually did it.
It was super simple and very cheap: a stretched, gessoed canvas and acrylic craft paint from the dollar store. I painted the canvas a pale blue, let it dry, and then painted our hands in descending order of size and pressed them on the canvas. The only thing I would do differently is put a small book inside the canvas stretcher to keep the canvas from moving when pressed and enable a better print.
I foresee an annual memento in the making.
