Schedule

FoldFest consists of four class sessions separated by 2-hour breaks. Each class session will be 4 hours long and contain two parallel tracks of presenters, all on Zoom (visit our Zoom tips page if you're new to using it).

Each session will be supported by an on-screen facilitator to interact live with the presenter, and a moderator in charge of the online Q&A. Participants may submit questions to the Q&A, which the moderator will either respond to, or elevate to the facilitator for live on-camera response. Note that we may not be able to answer every question live, but we will do our best to respond to every question. As always, please be respectful in your communications, as outlined in the OrigamiUSA Code of Conduct.

Here is a summary view of the schedule. Download a formatted PDF.

This model requires 8 equal-sized squares of paper, preferably kami or similar. The model includes a color change, so duo color paper is recommended. I recommend the squares have side-length 3” to 6” (3” should be fine, but larger might be good for less experienced folders).

Color change in origami refers to showing both sides of a sheet of paper in a single model. Including color changes in a model can be challenging but rewarding. In this talk, I will describe my origami design process and share tips for creating color-changed models.

Tessellations tickle many a scientist's fancy, but actually cramming thousands upon thousands of creases into any product is not always a stroll in the park. Join me for a romp through my two decades of (and my two cents on) origami engineering.

Infinity is a recursive modular design. Each unit is folded from one square and eight units are assembled to create a star. Consecutively smaller stars are then folded and assembled to create a spiral. You can theoretically fold and connect as many stars as you’d like since this is a recursive design. The model pictured has eight iterations of stars.

Supplies:

In this class, you will learn how to fold the units, assemble the units into stars, and connect the stars to create a spiral. You will need 8 square sheets of paper for the first iteration. I recommend 3” (15cm) squares of duo paper for your first time. You will also need to come prepared with extra paper and paper cutting / measuring tools to cut the paper for each additional iteration.

In this talk, we consider "refoldings" between two polyhedra. That is, you can refold a cube to a tetrahedron by unfolding a cube to a flat polygon and folding back up it into a tetrahedron. Many convex polyhedra can be joined by sequence of refolding, including all Platonic solids.
