Convention 2019 Broadcast Classes

Origami enthusiasts will have the opportunity to participate in Convention 2019, even if they can't attend: Broadcast Classes! And you don't need to be a member of OrigamiUSA to attend one. When you register for a Broadcast Class, you will be able to join selected classes via a live stream, with the option to ask questions of the instructor and interact with the other class attendees, as in on-site classes.

After you register for a Broadcast class, you will receive an email with details, guidelines and instructions on how to attend the class. You will need a computer connected to the Internet and a browser that supports the web-conferencing platform (test instructions will be included in the email).

You can view the class in real time and will also be able to view it after the event. You will be sent a link for the live event shortly before Convention begins. After the convention, you be sent the link for the recording.

Broadcast classes have a $10 fee for each class.

Broadcast Class Offerings



Knotology Cuboctahedron by Dasa Severova

Level: Intermediate

The knotology cuboctahedron is one of the simpliest polyhedrons that can be made with knotology, a technique developed by Heinz Strobl. It is a modular made from 6 paper strips. This class provides a good opportunity to begin working the knotology technique. Dimensions for the 6 strips (3 colors) are 2 cm × 21 cm (minimum). The strips will be provided for the class on site by the teacher. You should have some small clips to hold the strips together during the process.


Inflatable Mouse by Robert J. Lang

Level: Intermediate

This is an intermediate design, foldable from 10" kami. There is one open sink along the way.


Unicorn by Talo Kawasaki

Level: High Intermediate

It’s foldable, elegant and geometric — truly rare with origami for this mythical model. This model requires being able to fold numerous reverse folds and open sinks but it’s worth the adventure when you discover how Oriol Esteve developed this.



Closed Rose Dodecahedron by Robert J. Lang

Level: High Intermediate

This is a modular design, foldable from 6" kami, but shape-able paper (foil, wet-folding) works especially well. It takes 30 units; we'll plan to fold at least 10 during the class time, enough to demonstrate how to put the units together (which gets a bit tricky because there are flaps all over the place until it's assembled). Assembly is enormously aided if you bring a whole bunch of binder clips to hold things together during the assembly. They're not needed once everything is fully together.


Sakura (Cherry Blossom) by Deb Pun

Level: Intermediate

Learn Hoang Tien Quyet's lovely 5-petal sakura (cherry blossom) from a one-sheet 7 5/8-inch (20 cm) pink pentagon. It yields approximately 4 3/8-inch (10.5 cm) sakura. We will fold one variation to finish the sakura center in class, more if time permits. The sakuras in my picture menu show you at least three ways to complete the center of the flower. The model is folded from a pre-cut pentagon. Be comfortable folding sinks, pleats and swivel folds. Some folds do not have landmarks.


Rhombase Dragon No. 3 by Matthew Green

Level: High Intermediate

I will teach a dragon designed last year, using a base I discovered earlier in the year that I call the "rhombase." The dragon's distinguishing features are large wings, small legs, and a body with some volume. There are a lot of rabbit ear folds, normal and half petal folds, and shaping steps, including steps that don't lie flat. Participants should be familiar with all these folds by name. Recommended paper: 10" (25cm)
