Pleating without precreasing

In this class we'll fold tessellation-style pleated geometric patterns without precreasing. Each fold will be simple--just a pleat--and no folds will need to be undone. However, no reference points, or any other precreases will be used, and so you'll have to look at the folds you're making and pay attention to them as you work. Each student will be able to select a pattern from a "menu". Depending on your ambition (and granularity of your folding), it may take you slightly longer than the class period to finish.
