I see a lot of traffic coming here because people are doing searches for basic origami things; especially people searching for “origomi” instead of “origami”.
If that describes the reason you came to this site, I’d suggest the following links:
Bob Nienhuis’s money origami page
folds.net easy origami tutorials
Origami Underground (origami models for adults only)
British Origami Society
Marc Kirschenbaum’s Origami Page
Monkey.org tells you how to make an origami crane
Meenakshi’s huge page of modular origami diagrams
Sarah’s (of megatokyo fame) origami site
wannalearn.com’s links (many of the same sites, and several more for instructions
Hope that helps you get started down the road to some easy origami folding!
