INTRODUCTIONWon Park’s highly creative and intricate work has long been admired throughout the origami community. His“Where did you get it? This is my koi!” was Won’s reply. He explained that once in a while he would unfold a billdollar bill designs are some of the most challenging and popular, and there are legions of people around theand use it as spending money if the folding wasn’t proceeding to his liking.world who fold nothing but paper money. Despite the popularity of the form, only a relatively small numberof talented, creative artists publish money folds, and Won Park is widely regarded as a leading master of thisWe appreciate Won’s intricate designs even more when they are folded from larger rectangles of handmadespecialty.papers, such as the papers that we make here at Origamid Studio. Won folded a larger version of his Koi fromthis special, handmade paper, and we proudly displayed it to an enthusiastic response from the public.The US dollar bill is a popular format because it is readily available and relatively affordable, it is rich withintricate and artful engravings, and it is permanently printed on wonderfully strong, crisp stock. This mediumWon is also generous with his time.

What isMichael LaFosse and Richard Alexanderunusual is the combination of his eye for detail, his meticulous folding execution, and his finely tuned sense ofOrigamid Studioartistry. Some time ago, when we were setting up our Origami D show in Waikiki, Hawaii—a short drive fromWon’s house—we received a dollar as change from a local grocery clerk. It felt curiously soft, and upon closerexamination, we noticed it had been divided by dozens of crossing creases. We kept the bill safe until the nexttime we saw Won. We showed it to him and asked, “Do you recognize this?”

Are You Ready to Take theExtreme Origami Challenge?As with anything you do, origami—especially extreme origami—takes practice. Lots of practice. If you are already an advanced folder, youare well prepared to take the Extreme Origami challenge offered by this book. But if your skills are at an intermediate level, here are some When folding, compare the current step to the results in the step ahead. Sometimes knowing what the final result should look like will enable you toexecute a particularly difficult step.tips that will help you attack these models. Beware of overfolding. Paper softens with use—even durable stock like dollar bills—and when it is too soft, the folds won’t hold. Which is yet another Origami instructions can be tricky to follow. Most of the action is shown in the diagrams, but the text is important, too. Learn to read bothtogether to get the whole story. Some important folds are referred to by name; they are listed in the terms section. Read the terms through and learn them before you startthese models. Equip yourself with these basic tools when you are ready to begin folding:(1) Practice paper—use plain papers that are larger than (but with the same proportions as) regular dollar bills, if you can. They willmake the tiniest folds a little easier to learn. You will need to practice these models a lot before using real money to fold them. Oneof the challenges of folding with real money is that it has patterns and artwork printed on it that can make it hard to see the creases.So the value of getting up to speed on plain practice paper can’t be oversold.(2) A bone folder, for making sharp, accurate folds. Imprecise folds can throw the whole model off.(3) Tweezers, for grasping small folds firmly. It takes a bit of practice to learn how to use them properly.(4) Small paper clamps, for helping thickly folded paper to keep its shape.(5) Fresh, new dollar bills, for when you are ready to fold tight, crisp final models.good reason to practice, practice, practice. Sometimes you just need to step away from your project. These projects are extremely challenging. There will be times when you will throw your handsup in frustration. That’s when it is time to take a break and a breather. A little perspective always helps. Enjoy the process. Stay focused on making sharp, accurate folds and the rest will follow with time and practice. Allow yourself time to fold these models. They are works of art; making art takes time. Final shaping details are as important to the end product as theintermediate steps, so give these your full attention, too.
