Jacqueline Chong develops origami kits and conducts origami talks, workshops and events from time to time under the business name, Learning Squares. She holds a Diploma in the Montessori Method of Education (Early Childhood) and has 3 young children.
In 2005 she approached me for permission to develop one of my designs into a commercial calendar project. My "rhombic dodecahedron" unit is perfect for a calendar, simple to fold and holds together well. I suspect it wasn't a massive commercial success, but worth a shot.
The late "Creased" magazine featured it and you can print your own here.
This design is eminently suitable for all kinds of promotional gifts - please get in touch regarding licensing.
