Some tips for origami folding are to fold with clean hands, begin with a perfectly square sheet of paper for each object, use a ruler or inkless pen to create scores for folds, keep a staple gun or glue handy and use a bigger piece of paper than usual when creating a new model for the first time. Mistakes are common when doing origami, and if a fold is mistakenly made, it is best to start with a new sheet.
Making clean folds in origami is the key to a sharp and beautiful model. Before committing to a fold, create a soft crease along the intended fold line and check to make sure it is accurate. Use an object with a straight edge to assist in creating a sharp final crease. Some origami artists use special tools made of bone or plastic to create these scores and folds, but the back of a thumbnail or the back of a metal spoon also create clean and sharp creases. Thin but rigid paper, such as kami paper, is best for origami folding, but printer paper is fine for beginners.
Origami models are often time-consuming, but taking one's time and remaining patient is important to reduce and prevent mistakes. Always fold neatly and firmly, and take breaks when necessary.
