Origami is a complex, challenging and engrossing hobby. As you learn origami, you'll find there are two types of patterns: diagrams and crease patterns. Diagrams are just that: relatively easy step-by-step folding guides, ideal for beginners. Crease patterns, on the other hand, are the patterns made once origami is unfolded. To use them, you must interpret the crease lines to recreate the origami artists' steps. Sometimes, with complicated or original creations, and for proprietary reasons, a crease pattern is all that's available, such as for Kyubi, the nine-tailed fox from Naruto.
Locate an origami pattern you would like to try, using Google and Flickr. Unlike a crane, the Kyubi you'll find are original creations, so most artists will provide crease patterns only.
Print the crease pattern you wish to try.
Trace the crease pattern onto tracing paper to practice.
Identify the types of folds the pattern calls for. You will find that the majority of Kyubi patterns use mostly a frog base for the head, then box pleats, using Elias stretches to separate sections, such as the tails.
Fold, using your crease pattern.
This is a complicated design. If you are new to crease patterns, be prepared for many false starts before you're successful. If you're new to crease patterns, look for those which differentiate between hill and valley folds. If you run into trouble, make the tails shorter, rather than longer.
The crease patterns, diagrams and origami works you find are the property of the origami artists who have created them. While you can use the patterns they provide to make your Kyubi, you cannot use their ideas for profit.
