OrigamiUSA is the American national origami society. It offers origami resources via their website, magazines, online shop and conventions. Their website has a link to other origami groups, both in U.S. regional and international.
Portland Oregon Paper Shapers (POPS) is the local origami group in Portland, Oregon. It is a casual group that meets on every second Sunday afternoons at Belmont Library, as well on every third Sunday afternoons at Tualatin Public Library. Please note that POPS meetings at the libraries have been cancelled indefinitely due to the COVID-19 pandemic. In the meanwhile, POPS occasionally meet virtually on irregular basis. Please contact me directly if you’re interested in POPS virtual meetings.
Origami Paper, Books & Kits
Many art/craft/paper supply stores, bookstores, and Asian gift shops carry origami papers, books, and kits. There are also many online stores that carry them. Most origami papers are made in Japan so you will find the largest variety and at the lowest prices in Japan. As for origami books and kits, please find publication reviews on my Reviews page (here).
