Due to the resurgence of the Delta variant of COVID-19 and the resulting uncertainty over travel and gatherings, PCOC 2021 has been cancelled. Circumstances permitting, PCOC 2023 will be held at the same venue, the Parc 55 Hotel in San Francisco, sometime in the fall of 2023, with details to come closer to the event.

Instead, OrigamiUSA is planning to hold a set of online classes for World Origami Days 2021, October 24–November 11, similarly to the World Origami Days 2020 event. Further details will be posted toward the end of September.
