: Cut a slit along the folded edge and the open edge, but do not cut all the way through.

: Keep your scissors horizontal and make long, continuous cuts rather than small snips to avoid jagged edges.

If you need a physically long sheet of paper (e.g., over 100cm) for origami or large-scale art, you can join smaller pieces.

: When using a craft knife, apply just enough pressure to cut through the paper without sinking the blade into your cutting mat, which can cause drag and ruin curves.
