Hi,
My last convention to enjoy was in Germany. You can read about it here, in The Fold: https://origamiusa.org/thefold/article/convention-report-origami-deutschland -2015-bonn As I came back, I realized the Hilula tessellation I taught in the convention was quite popular, and many who posted images on Facebook were asked to share the instructions. So I just made a video tutorial here: https://youtu.be/bLYh5kMQBLc It is a unique tessellation, with just four pre-creases per molecule, and the collapse uses curves and not sharp folds. I hope you will enjoy it! Garibi Ilan Artist and Origami designer www.garibiorigami.com
