Thank you everyone for your help regarding how to teach dividing into thirds. Thanks to you guys, I learned some new methods!
I'm designing a paid origami class. I wish to edit free online diagrams, made by someone else, for folding a traditional model. I would digitally cut the different steps in order to make a slideshow showing just one step at a time along with its result. I would also add the name of the respective folds and bases to the slide. My idea is to project that for the class; I won't post it on the web nor share the files. 1. Do I need authorizaion from the diagrammer in order to do that? 2. If I don't edit the diagrams, do I still need authorization just to use the diagrams in the class? Thank you in advance guys. Hope to read you soon. Gerardo gerardo(a)neorigami.com
