Why are Holiday Tree folding sessions not open to Novice folders?

The reason we don't open the folding session for beginner folders is because all of the models that go on the tree should be exhibition quality, meaning impeccably folded for presentation in a professional exhibition at the American museum of natural history. There is a certain quality control that goes with decorating a tree for this huge event which is a showcase for OrigamiUSA and also a way to strengthen our bond with the museum. (We get office space and admin support because of this relationship). it is also a huge tourist attraction during the holiday season; thousands of people see the tree and many come to the museum just for it. In fact, because of the quality control requirements, not all models submitted get placed on the tree.
