One of my hobbies is origami. By the way, I occasionally teach origami classes. Contact me if you are interested in hiring me to teach an origami class. I am including instructions to fold my origami "Diamond Ring". Please feel free to copy these instructions for non-commercial purposes.
I made a little website that explains how to make your own origami paper. I took a web graphics class, and this was my final project. A lot of origami enthusiasts expressed an interest in my paper making technique. I hope this encourages you to give it a try.
