When I was 10 yo, I got an amazing origami book where I learned about origami "purism" philosophy - always using only one square sheet of paper, no cuts and no glue. What do you think about those self-imposed limitations for aesthetic reasons?
>>620948that is literally what origami is. what do you mean self-imposed? anything else is kirigami / paper craft.
>>620970It's a fairly modern convention. There are a number of traditional models that contain cuts.
>>620970What >>620972 said. Plus, folding non-square rectangular or other shapes of paper (triangles, pentagons, ...) is also origami (like money bills, teabag or chopstick wrappings, ...)
And to answer OP, I think self-restriction sometimes makes it more difficult to create - something like Kamiya's Ryujin from a square could more easily be obtained from a long rectangular string - but sometimes makes it easier - common bases, more symmetry, diagonals being medians, etc.
