According to Joseph Wu, "Origami is a form of visual / sculptural representation that is defined primarily by the folding of the medium (usually paper)."

No one really knows when origami was invented, only that it is an ancient art form that originated in Japan. In the late 1940's, New Yorker Lillian Oppenheimer saw an origami flapping bird at a family gathering and became enthralled with the art form. She began learning and teaching origami, and corresponding with paperfolders around the world. By 1980 her work, with the help of others, led to the founding of The Friends of The Origami Center of America, which in 1994 became OrigamiUSA.

The interest in origami today is widespread with many resources for enthusiasts. The first step in learning origami is to become familiar with the various folds. Next comes base figures, which are made from the folds. Base figures are the foundation for many origami structures. Once you can make base figures, you're ready for origami models!

If you're a beginner to origami try Paperfolding.com. Follow the instructions on the page and a pop-up window will open where you can click on Basic Folds. Here you'll find easy directions for fundamental origami folds, along with their names. Knowing folds by name will allow you to follow instructions for creating origami sculpture.

Basic folds include: Valley Fold, Mountain Fold, Petal Fold, Rabbit Ear Fold, Squash Fold, Inside Reverse Fold, Outside Reverse Fold, Crimp Fold, and Sink Fold.

Designating names to different folds is what makes learning and sharing origami easy. Without names, paperfolders would have to describe each fold in terms of corner, angle, direction, and so forth. It's much easier to simply say, "Make a petal fold," or "Follow that with a crimp fold."

After you've learned the folds, re-open the pop-up window and choose Base Figures. Base figures are noted as the starting point for many simple models. Each base figure is clickable and has folding instructions.

Base figures include: Preliminary Base, Birdbase, Extended Birdbase, Waterbomb Base, and Fishbase.

If you want a little inspiration you can go to the homepage of Paperfolding.com and explore the site to see some truly amazing origami.

When you're ready to create some origami, try the diagram link at Origami.com, for an excellent interface where you can view models based on complexity, then receive folding instructions for the origami you'd like to create. The instructions open in a .pdf file, so you'll need Acrobat Reader, which is free to download. The origami models contained in this file cover all skill levels, from beginners, to intermediate and advanced paperfolders.

Another great resource for practicing your paperfolding is Joseph Wu's origami site, where you'll find an entire page of origami sculptures from across the Web, most with simple folding instructions, just a click away.

Origami is an enduring art form -- some say as old as the invention of paper itself in 150 A.D. Whatever its origins, origami is certainly here to stay, and with a little practice you can join the millions of origami enthusiasts around the world celebrating the simple joy of paperfolding.
