Use thin and crisp paper. Origami paper (sometimes called kami) or photocopy paper will work. Don't use expensive paper at first.
Read the book from beginning. You must be familiar with the symbols and basic folds. Learn before folding.
Look at the diagrams carefully. Make sure you follow the sequence exactly as numbered. When lost, compare the diagram with the next one, and guess how to make it as described in the next diagram. If you can't figure out, begin again from the first step.
Fold neatly. Make sure the corners or edges exactly fit on each other. Don't make haste.
Fold firmly. Fold on a solid surface and press the creases with your fingers. Some folders use tools such as a folding-bone.
Practice and practice each model. No one can fold it well at the first time.
You can take a break when you feel tired or frusftrated. Leave it until tomorrow. Enjoy origami!
Wash your hands before you fold. It's important if you want to make a beautiful model.
Imagine what your model will be like, and choose suitable paper. Choose paper according to the model; or choose a model according to the paper.
Most models have their structures. You should understand them. And find out the best sequence. Change some folds if necessary. You don't have to follow the diagrams.
Fold rhythmically. Always be conscious of the whole sequence. To do so, you must fold from memory.
Fold in the air as far as possible, and you can feel the paper more.
Remember that paper has some thickness. Although you should fold neatly, you must give appropriate play.
Listen to the paper. Origami is collaboration by you and paper. Be friends with paper, and paper will hear you.
