Paper is visibly thin, flimsy; but it’s interesting that without anyone ordering that it be this way, the vast majority of origami models do not leave the cut edge of the paper exposed in the final model—which would make the model look flimsier still. It’s almost as if origami were ashamed of its material origins. A noted exception among well-known pieces is Herman Van Goubergen’s Cat. --Here and there no doubt, in a bi-plane or maybe a bird, the cut edge puts in an appearance, but on the whole this part of the square’s anatomy is kept firmly out of view, as the family embarrassment.
Paper fans are a famous exception to this rule. Partly this is because the visible structure is dominated by those long, strong, widening spans. But look at the difference between these two fans--the second of which hides the cut edge in a mountain fold. It is manifestly less alive, less free. One wants the end of those firm spans to have something that opens into, is as gentle as----the air.
I’ve noticed, following this line of thought, that featheriness (and not just in fan tails) is nicely expressed in paper by a cut edge, the paper’s flimsiness evidently serving as a nice stand-in for a feather’s quasi-substantiality.
And here’s an old model, the Flitting Bird, where(as my young friend Yuval Atlas once observed) if you don’t look straight at them, the wing-tips with their cut edge seem to be in motion.
So: are there any other rightful uses out there for the Cut Edge?
This blog has to start someplace; so it will start here. Don’t worry, pretty soon it will seem like I've been around forever.
